Question

5. If each side of a square is increased by 25%
its area is increased by​

Answer 1

Answer:

56.25%

Step-by-step explanation:

Let each side of the square be a. Then, area = .a2

New side =125a100=5a4. New area = (5a4)2 = (25a216)

Increase in area = 25a216−a2=9a216

Increase% = [9a216*1a2*100] % = 56.25%.
