Find the Perimeter rectangle (24)(18)

 $\begin{array}{r} l = & 24 \\ w = & 18 \end{array}$

Step 1

The perimeter of a rectangle is equal to the sum of all sides of the rectangle.

$l e n g t h + l e n g t h + w i d t h + w i d t h = 2 \cdot (l e n g t h) + 2 \cdot (w i d t h)$

Step 2

Substitute the values of the length $l = 24$ and width $w = 18$ into the formula for the perimeter of a rectangle.

$2 \cdot 24 + 2 \cdot 18$

Step 3

Simplify each term.

Multiply $2$ by $24$ .

$48 + 2 \cdot 18$

Multiply $2$ by $18$ .

$48 + 36$

$48 + 36$

Step 4

Add $48$ and $36$ .

$84$
