Answer:
If each side of a square is increased by 25%, find the percentage change in its area. Increase% = [9a216*1a2*100] % = 56.25%.
Answer:
Let each side of the square be a , then area = a^2
As given that the side is increased by 25%, then
New side = 125a/100 = 5a/4
New area = (5a/4)^2
Increased area= (25a^2/16)−a^2
Increase %= [(9a^2/16)a^2] x 100 % = 56.25%
Thank You!
