Find the area of square.if the perimeter of that square is 24cm

The perimeter $P$ of a square with side length $s$ is given by $P = 4s$.

We are given that the perimeter $P = 24$ cm.
So, $24 \text{ cm} = 4s$.
Divide both sides by 4:
$s = \frac{24 \text{ cm}}{4}$
$s = 6 \text{ cm}$

The area $A$ of a square with side length $s$ is given by $A = s^2$.

$A = (6 \text{ cm})^2$
$A = 36 \text{ cm}^2$

The area of the square is $36 \text{ cm}^2$.
