Question

by how much parcentage area of a squar will increease if its side is increased by 10%​

Answer 1

Step-by-step explanation:

increase in side = 10% =10/100 = 1/10

let original side = 10 ,

area of square= (side)^2

original area =(10)^2 = 100

new side = 10 + 1 = 11

new area = (11)^2 = 121

increase in area = 121 -100 = 21

increase% = 21/100 * 100

= 21% Answer
