Calculate the Perimeter of a Rectangular Garden

Maria is making a rectangular garden that will be 8 feet long and 3 feet wide. She wants to place a fence around the entire garden.

What is the total length of the fence Maria needs to buy?

To find the perimeter of a rectangle, you can use the formula:

$$P = 2(l + w)$$

where $l$ is the length and $w$ is the width.
