\begin{matrix} l = & 20 w = & 40 \end{matrix}

$\begin{array}{r} l = & 20 \\ w = & 40 \end{array}$

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 = 20

$l = 20$ and width

w = 40

$w = 40$ into the formula for the area of a rectangle.

20 \cdot 40

$20 \cdot 40$

Step 3

Multiply

20

$20$ by

40

$40$ .

800

$800$
