Question

What is the perimeter of a square that has an area of 25 square feet?

Answer 1

We know that the perimeter of a squate is (Where x is the side of the square):

`P=4x`

and we know that the area is:

`A=x^2`

So we can repace the area to find x so:

`\begin{gathered} 25=x^2 \\ x=\sqrt[]{25}=5 \end{gathered}`

So the perimeter will be:

`P=4\cdot5=20`

So the perimeter is 20 feet
