India’s size and area

Correct answer: A. Slightly greater

The correct answer is A, slightly greater. India’s north-south extent is approximately 3,214 km, measured from the northern Himalayan region to the southern end of the mainland, whereas its east-west extent is about 2,933 km. The difference is roughly 281 km, so the north-south dimension is longer, but not dramatically so. Option B reverses the comparison, and option C ignores the measurable difference between the two dimensions. Option D is clearly unreasonable because India is a large country in both directions. These figures describe the country’s overall size and help explain why India has considerable variations in climate, vegetation, and local time.

Correct answer: B. About 6,100 km

The correct answer is B, approximately 6,100 km. This value describes the coastline of India’s mainland along the Arabian Sea, the Indian Ocean and the Bay of Bengal. It excludes the separate coastlines of the Andaman and Nicobar Islands and Lakshadweep. That distinction is important because the total coastline of India including islands is approximately 7,516.6 km. Option A is too low, while options C and D substantially overstate the mainland figure. Coastline measurements can differ slightly with scale and surveying method, but 6,100 km is the conventional rounded figure used in school geography for the mainland coastline.

Correct answer: C. Asia

The correct answer is C, Asia. India is located in South Asia and covers about 3.28 million square kilometres, making it one of the continent’s major countries by area. It is commonly described as the seventh-largest country in the world by area and one of Asia’s largest states. Africa and Australia are separate continents, so India cannot be counted as a major country within either of them. Europe is also a different continent, although India’s area is larger than that of most individual European countries. The question asks for the continent, not India’s subregional name; therefore South Asia is the location within Asia, while Asia is the required answer.

Correct answer: A. square kilometres

The governing concept is dimensional measurement: area describes the amount of two-dimensional surface occupied by a region, so it must be expressed in square units. India’s area is commonly given as about 32.8 lakh square kilometres, written as 3.28 million km². Option A is correct because km² represents length multiplied by breadth. Kilometres measure one-dimensional distance, so option B cannot express area. Metres per second is a unit of speed, making option C irrelevant. Degrees Celsius measure temperature, not surface size, so option D is also incorrect. The word area should immediately prompt a square unit such as m² or km².

Correct answer: A. Longitudinal extent

The governing concept is the relationship between longitude and local time. Earth rotates 360 degrees in about 24 hours, so a difference of 15 degrees of longitude corresponds approximately to one hour of time. India extends from about 68°7′ E to 97°25′ E, a difference of roughly 29 degrees; this creates nearly two hours of local-time difference between the western and eastern parts. Soil, river water and vegetation do not determine clock time. To avoid administrative confusion, India uses one Standard Time based on 82°30′ E. Thus, option A, longitudinal extent, is correct.

Correct answer: A. 8°4′ N

The governing concept is the latitudinal extent of India’s mainland. The mainland stretches from approximately 8°4′ N in the south to about 37°6′ N in the north. Therefore, the southern starting latitude is 8°4′ N, making option A correct. The value 23°30′ N is associated with the Tropic of Cancer, which crosses the middle part of India, while 37°6′ N marks the northern limit of the mainland. The value 82°30′ E is a longitude used for Indian Standard Time, so it cannot answer a latitude question. Careful attention to N and E prevents confusion between latitude and longitude.

Correct answer: A. Three point two eight million square kilometres

India has a total area of approximately 3.28 million square kilometres, commonly written as about 3,287,263 square kilometres. Therefore option A is correct. The figure represents the country’s land area and is a standard fact in the study of India’s size and location. Option B, one million square kilometres, is far too small; option C, five million, and option D, ten million, are substantially larger than India’s actual area. The Hindi wording in option A corresponds to about thirty-two lakh eighty-seven thousand square kilometres, which is the rounded value of the standard figure. Do not confuse area with linear latitudinal or longitudinal extent, because area is measured in square kilometres.

Correct answer: A. Seventh

By total geographical area, India is the seventh-largest country in the world. Thus option A is correct. The ranking is based on area, not on population, economic output, or any other measure. The largest countries by area include Russia, Canada, China, the United States, Brazil, and Australia, followed by India in seventh place in the commonly used school-geography ranking. Option B and option C give ranks that are too high, while option D gives a rank that is too low. A helpful exam precaution is to read the phrase “by area” carefully: India’s position in population rankings is a different fact and must not be substituted for its area rank.

Correct answer: C. 2.4 percent

The correct answer is 2.4 percent because India occupies approximately 3.28 million square kilometres, while the world's total geographical area is roughly 136 million square kilometres when land and inland water areas are considered. The ratio is therefore close to 3.28 ÷ 136 × 100, which is about 2.4 percent. This share may appear small, but it represents a very large and geographically varied territory. Option A underestimates India's share, whereas B and D greatly overstate it. The governing concept is comparison of a country's area with the total area of the world.

Correct answer: D. Square kilometres

The correct unit is square kilometres because area measures the amount of two-dimensional surface covered by a country. A square kilometre represents a square measuring one kilometre on each side, so it is written as km². Kilometres per hour and metres per second are units of speed, not area; they describe how fast something moves. Degree Celsius measures temperature. India’s area is therefore reported in square kilometres, commonly as about 3.28 million km². The governing concept is matching a physical quantity with its proper unit: length uses kilometres, area uses square kilometres, and temperature uses degrees Celsius.

Correct answer: A. Natural and cultural diversity

Natural and cultural diversity is the correct result of India’s large area. A vast territory extends across mountains, plains, plateaus, deserts, coasts and islands, so relief, temperature, rainfall, soils, vegetation and wildlife vary considerably. Large spatial extent also permits many historical regions, languages, communities, traditions and economic activities to develop. The other choices contradict geographical evidence: a large country does not have identical climate everywhere, it contains several soil types, and it clearly has regional differences. The governing concept is that greater areal extent usually includes more environmental zones and human landscapes, producing diversity rather than uniformity.

Correct answer: B. 3.28 million square kilometres

India’s area is approximately 3.28 million square kilometres, so option B is correct. In Indian geography texts this is also written as about 3,287,263 square kilometres, or roughly 32.8 lakh km². The question asks for the closest approximate value, not an exact survey measurement, so remembering 3.28 million km² is sufficient. The values 1.5, 6.5 and 12 million km² are respectively too small or much too large compared with India’s accepted area. The governing concept is estimation and scale: India is a very large country, but its area is far below the areas of the largest countries such as Russia and Canada.

Correct answer: C. Large country

India is considered a large country at the world level because its area is about 3.28 million square kilometres and it ranks among the largest countries by geographical extent. Its size includes a long north–south and east–west spread, varied physical regions and a substantial share of the Asian landmass. The description “large country” refers to area, not to whether India is an island or a microstate. A medium island, very small country and microstate are all incompatible with India’s continental-scale territory. The governing concept is interpreting national size comparatively: a country’s status is understood by comparing its area with the areas of countries worldwide.

Correct answer: D. They are larger than India

Six countries are larger than India in area, so option D is correct. India is commonly described as the seventh-largest country in the world by geographical area. In an ordered ranking, first place is the largest, and a country in seventh place has six countries ahead of it; therefore six countries have greater areas than India. The statement does not mean that only six countries exist or that those countries lie inside India. Option A reverses the ranking, B incorrectly suggests equal area, and C confuses area comparison with location. The governing concept is reading ordinal rank and translating it into a comparison of areas.

Correct answer: A. Russia

Russia is larger than India in area, making option A correct. Russia covers roughly 17.1 million square kilometres, whereas India covers about 3.28 million square kilometres. Russia therefore has a much greater geographical extent and is the largest country in the world by area. Nepal, Bhutan and Sri Lanka are all much smaller than India; Nepal and Bhutan are neighbouring Himalayan countries, while Sri Lanka is an island country south of India. The governing concept is comparative area, not population, political importance or physical distance. A country being a neighbour or an island does not determine whether it is larger; the relevant evidence is its measured land area.

Correct answer: B. Nepal

Nepal is the correct answer because it is a neighbouring country with an area of about 147,000 square kilometres, far smaller than India’s approximately 3.28 million square kilometres. China is India’s neighbour but has a much larger area; Russia and Canada are also far larger than India, although they are not usually listed as India’s immediate land neighbours in this context. The question tests both relationship and size: the country must be a neighbour and smaller in area. Nepal satisfies both conditions. The governing concept is comparing the geographical extent of India with the areas of countries around it, rather than confusing population, altitude or political importance with area.

Correct answer: C. Due to vast size and diversity

India has subcontinental importance because of its vast size combined with exceptional physical and cultural diversity, so option C is correct. The Indian landmass is large enough to contain the Himalayas, northern plains, peninsular plateau, deserts, coastal plains and islands, along with varied climates, soils, ecosystems, languages and traditions. This combination gives India a distinctive regional identity and geographical significance within Asia. A very small size cannot create subcontinental scale; India is not an island, and it does not have a polar location. The governing concept is that a subcontinent is a large, distinct geographical region with internal diversity and some degree of physical separation.

Correct answer: D. 15200 kilometres

India’s land boundary is approximately 15,200 kilometres long, so option D is correct. This measurement refers to the international land frontier around India’s mainland and is distinct from the coastline, which is measured separately. The figure helps show the enormous spatial extent of the country and the length of its boundaries with neighbouring states. Three thousand and seven thousand kilometres are substantial but too short for India’s land frontier, while ten thousand kilometres is still below the accepted approximate figure. The governing concept is distinguishing types of boundary measurement: land boundary is not the same as coastline, and neither should be confused with India’s north–south or east–west extent.

Correct answer: C. It increases

A coastline is the boundary where land meets the sea. If only mainland India is measured, the calculation includes the shore of the continuous mainland. Islands are also land areas surrounded by water, so every included island contributes its own shoreline to the national total. Adding these island coastlines to the mainland coastline increases the measured length. Therefore, option C is correct. The coastline does not decrease because no mainland shore is removed; it does not become zero because the land still meets the sea; and it does not disappear because islands themselves possess coastlines. The exact total may vary slightly according to mapping scale and measurement method, but the direction of change is always an increase when additional island shores are included.

Correct answer: D. India is among the large countries of the world

The correct answer is D. The governing concept is the relative size of India in the world: with an area of about 3.287 million square kilometres, India is one of the world’s large countries and is commonly ranked seventh by area. This large extent helps explain its varied landforms, climates, soils, resources and human regions. Option A is the opposite of the established fact. Option B is false because India has extensive mainland coasts as well as island coasts. Option C is also false because most of India’s area lies on the mainland, not only on islands.

Correct answer: A. Climate and resource distribution

The correct answer is A because geographical vastness influences the spatial pattern of climate and the distribution of natural resources within India. The governing concept is that a large country may extend across different latitudes, landforms, elevations and distances from the sea. These controls produce regional differences in temperature, rainfall, soils, vegetation, minerals, water and agriculture. India’s large extent therefore creates considerable geographical diversity. Options B, C and D concern astronomical properties that are not changed by India’s size. India’s area can affect local and regional conditions, but it cannot alter the Sun’s age, Earth’s orbit or the Moon’s dimensions.

Correct answer: B. 32.87 lakh square kilometres

The correct answer is B: India’s area is approximately 32.87 lakh square kilometres, or about 3.287 million square kilometres. The governing concept is conversion between Indian and international units. Since one lakh equals 100,000, 32.87 lakh equals 32.87 × 100,000 = 3,287,000 square kilometres, which is 3.287 million square kilometres. Option A is far too small, while C and D are considerably larger than the accepted value. The word approximately is important because published figures may be rounded slightly, but they remain close to 32.87 lakh square kilometres.

Correct answer: A. About 32.8 lakh square kilometres

This question tests the conversion between million and lakh. In the Indian numbering system, one million is equal to ten lakh. Therefore, 3.28 million means 3.28 multiplied by 10 lakh, which gives 32.8 lakh. In ordinary international notation, this is 3,280,000 square kilometres. The unit remains square kilometres throughout the conversion because only the number is being rewritten in another counting system.

Option A is correct because 3.28 million and 32.8 lakh represent exactly the same quantity. The other options are much smaller: 3,000, 300, and 1 lakh square kilometres cannot represent the area of India. A common mistake is to read “million” as “lakh” without applying the factor of ten. Remembering that 1 million equals 10 lakh avoids that error.

Correct answer: C. Australia

The correct answer is C, Australia. The governing concept is comparative area: India covers about 3.287 million square kilometres, whereas Australia covers roughly 7.7 million square kilometres, so Australia is substantially larger. India is generally ranked seventh among countries by area, while Australia is among the six countries larger than India. Bhutan, Sri Lanka and Maldives are all much smaller than India. The comparison is based on total national area, not population, economic size or coastline length. Thus, even though India is a very large country, Australia is the only option listed that exceeds it in area.

Correct answer: D. Bangladesh

The correct answer is D, Bangladesh. The governing concept is comparison of national areas. India covers about 3.287 million square kilometres, whereas Bangladesh covers approximately 148,000 square kilometres, so India is much larger. Canada, Russia and China are all among the countries whose areas exceed India’s area, making them unsuitable answers. Bangladesh is also India’s neighbour, but the answer depends on area rather than geographical proximity alone. This question tests whether learners can distinguish India’s large size from the smaller size of a neighbouring country. Therefore, D is the only correct option.
