Chapter 1: Q44. (page 8)

Which expression best represents the perimeter of the rectangle.
$\begin{array}{l} F) \frac{r^{4}}{9} \\ G) l + w \\ H) 2 l + 2 w \\ J) 4 (l + w) \end{array}$

Short Answer

Expert verified

The expression for the area of the rectangle is $H) 2 l + 2 w$ .

Step by step solution

Step 1. The perimeter of the rectangle.

The perimeter of the rectangle is $2 (L + W)$ , where $L$ is the length of the rectangle and $W$ is the width.

Step 2. Put the value of length and width into the perimeter formula.

From the given figure, the length and width of the rectangle is $l a n d w$ respectively.

Put $L = l a n d W = w$ into the formula $2 (L + W)$ .

$P e r i m e t e r = 2 (l + w)$

Step 3. Remove the parenthesis.

$\begin{array}{l} P e r i m e t e r = 2 (l + w) \\ P e r i m e t e r = 2 l + 2 w \end{array}$

Hence, the correct option is $H) 2 l + 2 w$
