Question

If each side of the square is increased 25%. Find the percentage change in it's area. ​

Answer 1

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 2

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%
