Question

If side of a square is doubled, then the new perimeter is ________ times the original perimeter.

Answer 1

Let the side of square be x units.
$\therefore$ Perimeter = 4x units
New side of square = 2x units
$\therefore$ New perimeter = 4 $\times$ 2x = 8x units
= 2 $\times$ 4x = 2 $\times$ original perimeter
