Find the Perimeter rectangle (12)(12)

 $\begin{array}{r} l = & 12 \\ w = & 12 \end{array}$

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 $l = 12$ and width $w = 12$ into the formula for the perimeter of a rectangle.

$2 \cdot 12 + 2 \cdot 12$

Step 3

Simplify each term.

Multiply $2$ by $12$ .

$24 + 2 \cdot 12$

Multiply $2$ by $12$ .

$24 + 24$

$24 + 24$

Step 4

Add $24$ and $24$ .

$48$
