Question

on increasing each side of a a Square
by 25%, how
how many percent with its
area increase ?​

Answer 1

Answer:

Let the side of square be x.

Area of square = $x^{2}$

New side of square = 125% of x = 1.25x

New area = 1.25x * 1.25x = $1.5625x^2$

Hence, percentage increase in area = 1.5625 * 100 = 156.25%
