Why is writing India's area (3.28) million km instead of (3.28) million sq km incomplete?

Answer and explanation

Correct answer: Because area needs square km

Area measures the surface covered by a place, so it has two dimensions: length and breadth. When these dimensions are multiplied, the unit becomes square kilometres, written as km² or sq km. India’s area is therefore expressed as 3.28 million square kilometres. Writing only million km gives a unit of length, not a unit of surface area, so the measurement is incomplete and potentially misleading.

Option A is correct because area requires square kilometres. Percent is a way of showing a share and is not the necessary unit for every area measurement. A kilometre does not show rank; it measures distance. India certainly has an area, so option D is plainly false. The essential rule is to use ordinary kilometres for distance and square kilometres for area.
