\begin{array}{r} l = & 10 \\ w = & 20 \end{array}

$\begin{array}{r} l = & 10 \\ w = & 20 \end{array}$

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 = 10

$l = 10$ and width

w = 20

$w = 20$ into the formula for the area of a rectangle.

10 \cdot 20

$10 \cdot 20$

Step 3

Multiply

10

$10$ by

20

$20$ .

200

$200$
