Question

the side of the square is 10 cm. how many times will the new perimeter becomes the side of the square is double

Answer 1

Side of square = 10
Perimeter = 4 × side
= 4 ×10
= 40cm

When sides are doubled:-
Sides = 2×10
= 20

New perimeter = 4 (side)
= 4 × 20
= 80

So when the sides of square is doubled the perimeter will also doubled.

If you satisfied mark it brainliest.

Answer 2

Hey mate .... ☺

Here's ur ans. ----

Perimeter of square =4a ( a=side of square)

P1 = 4×10
P1 = 40cm^2

Side is doubled (a')= 2a = 2×10 =20

Perimeter of new square = 4 × a'
P2 = 4×20 = 80

Therefore
P2/P1 = 80/40 = 2

Hence perimeter is also doubled .
