Q. A square garage door has sides that are

4\,\text{yards}

long. What is the garage door's perimeter?

\newline

\_\_\_\_\_

yards

Identify Formula: Identify the formula for the perimeter of a square. $\newline$ The formula for the perimeter of a square is $P = 4s$ , where $P$ is the perimeter and $s$ is the length of one side.
Plug in Value: Plug in the value of $s$ in $P = 4s$ . $s = 4$ yards $P = 4s$ Replace $s$ with $4$ $P = 4 \times 4$
Calculate Perimeter: Calculate the perimeter. $\newline$ P = $4 \times 4$ $\newline$ P = $16$ yards
State Length: State the length of the perimeter of the square garage door. $\newline$ The perimeter of the square garage door is $16$ yards.
