Question

the side of a square is 10 cm.oe many times will the new perimeter become if the side of the square is doubled

Answer 1

(1) Perimeter =4×10 (perimeter of square = 4×side)
=40 cm

Doubling the side 2×10=20cm
Perimeter after doubling the side
here the side =20cm

(2) new perimeter =4×20
=80cm



new perimeter is 2 times of previous perimeter
40X=80cm
X=80/40
X=2
