\begin{array}{r} l = & 7 \\ w = & 3 \end{array}

$\begin{array}{r} l = & 7 \\ w = & 3 \end{array}$

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 = 7

$l = 7$ and width

w = 3

$w = 3$ into the formula for the area of a rectangle.

7 \cdot 3

$7 \cdot 3$

Step 3

Multiply

7

$7$ by

3

$3$ .
