Question

If the side of a square is increased by 25%, then its area is increased by​

Answer 1

Answer:

Step-by-step explanation:

Given each side of square = x

Increased side = 1.25x

Old Area = x^2

New Area = (1.25x)^2 = (1.25)^2 * x^2

                 = (25/16)(x^2)

Increased Area In Percentage = ((New-Old)*100)/Old

                                                  = ((9/16)(x^2)*100)/x^2

                                                  = 900/16 = 56.25 %
