Question

3. When each side of a square is reduced by 3 metres the area becomes 64 square metresFind the side of original square.​

Answer 1

Answer:

121

Step-by-step explanation:

Area of square=side*side

let the original side be x

then original area=x*x

new side=x-3

new area =(x-3)*(x-3)=(x-3)^2 =64

x-3=8

x=11

the original area is 11*11=121
