Chapter 11.1, Problem 5CE

To determine

To Find: The perimeter.

Answer to Problem 5CE

  $P=32cm$

Explanation of Solution

Given: The area of the square is $64c{m}^2$ .

Given:

Area of square= $64c{m}^2$

Then

Area of square

  $\begin{array}{l}A=s^2\\ $ 64={(s)}^2$s=\sqrt{64}\\ s=8cm\end{array}$

The side of the square is $8cm$

Now,

Perimeter of square

  $\begin{array}{l}P=4s\\ P=4(8)\\ P=32cm\end{array}$

Hence, $P=32cm$
