यदि किसी region की density 800 व्यक्ति प्रति वर्ग किलोमीटर है और total population 640000 है, तो area कितना होगा?
Explanation opens after your attempt
C. 800 वर्ग किलोमीटर800 square kilometres
Simple Explanation
Area \(= Population/Density\)। इसलिए \(640000/800 = 800\) square kilometres। तीसरा विकल्प सही है। Check करने पर \(800 \times 800 = 640000\) मिलता है। इस तरह formula and verification दोनों answer consistency दिखाते हैं। / Area equals population divided by density. Therefore, \(640000/800 = 800\) square kilometres. The third option is correct. A check gives \(800 \times 800 = 640000\), confirming the result. Using both the formula and a reverse multiplication check helps ensure consistency.
