Question

The Area Of A Square Is 900 cm2 Find The Perimeter Of The Square

Answer 1

Step-by-step explanation:

area =a^2

900=a^2

a=√900 cm

a=30 cm

therefore PERIMETER=30×4=120 cm

• answer =perimeteris 120 cm

Answer 2

Answer:

The perimeter of the square will be 120 cm.

Step-by-step explanation:

Given: The area of a square is$900cm^2$.

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$900cm^2$.

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:

$Area = side ^{2} \\900= side ^{2} \\ side =\sqrt{900} \\ side =30\ \ \ ....[30\times30=900]$

So, the side of the square will be 30 cm.

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:

$P=4a$

$P=4\times30\\P=120$

Hence, the perimeter of the square will be 120 cm.
