Q. If the side lengths of a square are doubled, then how much area will be increased?
(A) 3 times
(B) 5 times
(C) 2 times
(D) 4 times
Question from UPPSC Prelims CSAT 2024
The correct answer is: (A) 3 times
Explanation:
– Original area = s^2
– New side length = 2s, so new area = (2s)^2 = 4s^2
– Increase in area = 4s^2 – s^2 = 3s^2
Thus, the area increases by 3 times.
