Question

The side of a square is 10 cm. How many times will the new perimeter become, if the side ofthe square is doubled?

1 point

(a) 2 times

(b) 4 times

(c) 6 times

(d) 8 times

​

Answer 1

Answer:

2 times

Step-by-step explanation:

first 4*10=40

then if side becomes double 4*20=80

Answer 2

Answer:

Your answer is

(A) 2 times

Step-by-step explanation:

We have given -

Side of square1 = 10cm.

So, perimeter of square = 4×(Side)

Perimeter = 4×(10) = 40cm.

If the side of the square1 is double,i.e.,

10×2= 20cm.

So the perimeter of the square2 = 4×(20) = 80cm.

so, to find the ratio or the number of times =

Perimeter of square2 = 80 = 2

Perimeter of square1. 40

so The perimeter of the square is doubled

And hence (A) is your correct answer
