\begin{matrix} l = & 9 w = & 9 \end{matrix}

$\begin{array}{r} l = & 9 \\ w = & 9 \end{array}$

Step 1

The area of a rectangle is equal to the length times the width.

(l e n g t h) \cdot (w i d t h)

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

Step 2

Substitute the values of the length

l = 9

$l = 9$ and width

w = 9

$w = 9$ into the formula for the area of a rectangle.

9 \cdot 9

$9 \cdot 9$

Step 3

Multiply

9

$9$ by

9

$9$ .
