# You are laying an asphalt driveway. How much area must you cover if the driveway is 21 feet long and 10.5 feet wide?

This driveway, we assume, is rectangular in shape.

To find the area of the driveway, you can use the formula for the area of a rectangle:

[ \text{Area} = \text{Length} \times \text{Width} ]

Given:

- Length of the driveway = 21 feet
- Width of the driveway = 10.5 feet

Substitute these values into the formula:

[ \text{Area} = 21 \times 10.5 ]

[ \text{Area} = 220.5 ]

Therefore, you must cover an area of 220.5 square feet for the driveway.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
