## What is area?

**Area**is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

For example, the rectangle below has an area of $12$ square units because it

## Area of a rectangle formula

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

### Example 1:

$\text{Area}=\text{length}\times\text{width}$

$\phantom{\text{Area}}=6\times2$

$\phantom{\text{Area}}=12\text{ square units}$

$\phantom{\text{Area}}=6\times2$

$\phantom{\text{Area}}=12\text{ square units}$

### Example 2:

$\text{Area}=\text{length}\times\text{width}$

$\phantom{\text{Area}}=7\times4$

$\phantom{\text{Area}}=28\text{ square units}$

$\phantom{\text{Area}}=7\times4$

$\phantom{\text{Area}}=28\text{ square units}$
