Question

the area of a square is 9cm2 find the perimeter of the square​

Answer 1

Answer:

12cm

Step-by-step explanation:

Given - area of square = 9 cm^2

To find - Perimeter

since area of square is (side)^2

let the side be x

x^2 = 9

x = √9

x= 3 cm

perimeter of square = 4* side

4* x

4*3

= 12 cm

Answer 2

Answer:

The perimeter of the square will be 12cm.

Step-by-step explanation:

Given: The area of a square is$9cm^2$.

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$9cm^2$.

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:

$Area = side ^{2} \\9= side ^{2} \\ side =\sqrt{9} \\ side =3\ \ \ ....[3\times3=9]$

So, the side of the square will be 3cm.

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:

$P=4a$

$P=4\times3\\P=12$

Hence, the perimeter of the square will be 12cm.
