Calculating Perimeter of a Rectangle

Maria is designing a rectangular garden that is to be 4 meters long and 3 meters wide. She wants to know the total distance around the garden, which is called the perimeter.

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

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

where:

- $P$ is the perimeter

- $l$ is the length

- $w$ is the width

What is the perimeter of Maria's garden?
