# The area of the square is 169 square ft how do you find the perimeter of the square?

$P = 52 f t$

#### Explanation:

The perimeter of a square is
$P = 4 \cdot l$

Whereas the area of a square is
$A = {l}^{2}$

So we have that
$\sqrt{A} = l = \sqrt{169} = 13 f t$

And therefore the perimeter is
$P = 4 \cdot 13 = 52 f t$
