Let each side of the square be a. Then, area = .a2a2

New side =125a100=5a4125a100=5a4. New area = (5a4)25a42 = (25a216)25a216

 

Increase in area = 25a216−a2=9a21625a216-a2=9a216

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

Answer 2

if each side of a square is increased by 25%, what is the percentage change in its area? if the side of the square is x, then the increased side of the square is 1.25x The difference percentage of the area of the square is = (1.5625 x^2 / x^2) * 100% = 56.25%
