Q. The surface of a rectangular table is

8\,\text{feet}

long and

3\,\text{feet}

wide. What is its perimeter?

\newline

\_\_\_\_\_

feet

Identify Formula: Identify the formula for the perimeter of a rectangle. $\newline$ The formula for the perimeter of a rectangle is $P = 2(l + w)$ , where $l$ is the length and $w$ is the width.
Plug in Values: Plug in the values of $l$ and $w$ into the formula. $\newline$ Given $l = 8$ feet and $w = 3$ feet, we have $P = 2(8 + 3)$ .
Perform Addition: Perform the addition inside the parentheses. $\newline$ P = $2$ ( $11$ )
Multiply to Find Perimeter: Multiply the sum by $2$ to find the perimeter. $\newline$ P = $2 \times 11$ $\newline$ P = $22$ feet
