Question

The perimeter of a square equals 4 times the length of side of the square. How long is the side if the perimeters is 64 feet ?

Answer 1

Let l be the length of the side. The perimeter is given by:

$P=4l$

If the perimeter is 64 ft then we have:

$\begin{gathered} 4l=64 \\ l=\frac{64}{4} \\ l=16 \end{gathered}$

Therefore the length of the perimeter is 16 ft
