Question

let the area of a square is 9cmsquare. what would be the new area. if its side its reduced by 1cm.

Answer 1

area of square = a×a
area of square = 9
side= root 9
=3
side =3
reduced by 1= 3-1
= 2
new area= 2×2
=4

Answer 2

Area of square = 9 cm^2
(Side)^2 = 9
Side = √9
Side = 3 cm
New side = 3 - 1 = 2 cm
Area = (Side)^2
= 2 × 2 = 4 cm^2
