Find the area of a square of perimeter 12 cm?

Firstly, we have to find the length each side of the square.

The formula to find the area is

To find the area of a square with a perimeter of 12 cm, you first need to find the length of one side of the square. Since a square has all sides equal, you can divide the perimeter by 4 to find the length of one side. Once you have the length of one side, you can calculate the area of the square by squaring that length.

Let's denote the length of one side of the square as ( s ).

Given that the perimeter of the square is 12 cm, we have:

( 4s = 12 )

Solving for ( s ), we find:

( s = \frac{12}{4} = 3 ) cm

Now that we know the length of one side (( s = 3 ) cm), we can calculate the area of the square using the formula:

( \text{Area} = s^2 )

Substituting the value of ( s ), we get:

( \text{Area} = 3^2 = 9 ) square centimeters

So, the area of the square is ( 9 ) square centimeters.
