Q. A square family room has sides that are

5\,\text{meters}

long. What is the family room's perimeter?

\newline

\_\_\_\_\_

meters

Understand Formula: Understand 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 of the square.
Plug in Value: Plug in the value of $s$ into the formula. $\newline$ Since each side of the square family room is $5$ meters long, we substitute $s$ with $5$ in the formula $P = 4s$ . $\newline$ $P = 4 \times 5$
Calculate Perimeter: Calculate the perimeter. $\newline$ Multiplying $4$ by $5$ , we get: $\newline$ $P = 20$ meters
Final Answer: State the final answer. $\newline$ The perimeter of the square family room is $20$ meters.
