Question

Side of a square is 10cm its side is tripled then by how many times will its perimeter increases

Answer 1

The perimeter of square of side 10cm is 40 CMS.

If the side is tripled then the side becomes 30 CMS.

It's perimeter is 4(30)=120

it is 4 times the original perimeter.

Answer 2

3 times will its perimeter increases.

Step-by-step explanation:

Given : Side of a square is 10 cm its side is tripled.

To find : How many times will its perimeter increases?

Solution :

The side of a square is a=10 cm.

Perimeter of the square is $P=4a$

i.e. $P=4\times 10$

$P=40\ cm$

Its side is tripled i.e. a=3(10)=30

The new perimeter is

$P_n=4\times 30$

$P_n=120$

We have to find how many times the new perimeter is

i.e. $Px=P_n$

$40x=120$

$x=\frac{120}{40}$

$x=3$

Therefore, 3 times will its perimeter increases.
