Imagine you have a rectangular garden. The length of the garden is 6 meters and the width is 4 meters. To find out how much fencing you need to put around the garden, you can calculate the perimeter.
The formula for the perimeter (P) of a rectangle is given by:
$$ P = 2(l + w) $$
In this formula, $l$ represents the length and $w$ represents the width. Use this information to determine the perimeter of the garden.
