Q. Each side of a square playpen is

4

feet long. What is the playpen's area?

\newline

\newline

\_\_\_\_

square feet

Identify formula: Identify the formula for the area of a square. $\newline$ Area formula is $A = s^2$ , where $s$ is the length of one side.
Plug in value: Plug in the value of $s$ into the formula. $s = 4$ feet, so $A = 4^2$ .
Calculate area: Calculate the area. $\newline$ $4^2 = 16$ , so the area is $16$ square feet.
