\begin{matrix} l = & 4 cm w = & 7 cm \end{matrix}

$\begin{array}{r} l = & 4 cm \\ w = & 7 cm \end{array}$

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 = 4

$l = 4$ and width

w = 7

$w = 7$ into the formula for the area of a rectangle.

4 \cdot 7

$4 \cdot 7$

Step 3

Multiply

4

$4$ by

7

$7$ .
