Question

Find the perimeter and area of a square with a 12 feet side

Answer 1

We can find the perimeter and the area of the square using the formulas:

Then

$\begin{gathered} A=\ell^2 \\ P=4\ell \end{gathered}$

Where l is the side of the square, where it's 12 feet, then

$\begin{gathered} A=12^2=144\text{ ft}^2 \\ P=4\cdot12=48\text{ ft} \end{gathered}$

The area is 144 ft squared and the perimeter is 48 feet.
