Question

if the area of the square is 100cm square
find its perimeter​

Answer 1

Answer:

40 cm

Step-by-step explanation:

area of a square is side ( square).

area=100 cm square

=10 square

there side of the square is 10 cm.

perimeter of a square is 4*(side)

=4*10

40cm.

therefore the perimeter of the square is 40 cm.

Answer 2

Answer:

The perimeter of the square will be 40cm.

Step-by-step explanation:

Given: The area of a square is$100cm^2$.

We have to find the perimeter of the square.

• As we know that the formula is used to calculate the area of the square is: $Area = side ^{2}$  

We are solving in the following way:

We have,

The area of a square is$100cm^2$.

Here we have the area of the square, so first, we will find the side of the square.

The side of the square will be:

$Area = side ^{2} \\100= side ^{2} \\ side =\sqrt{100} \\ side =10\ \ \ ....[10\times10=100]$

Hence, the side of the square will be  10cm.

We know that,

• The perimeter of the square is calculated by a formula:$P=4a$

Where a is the side of the square.

So, the perimeter of the square will be:

$P=4a$

$P=4\times10\\P=40$

Hence, the perimeter of the square will be 40cm.
