Calculating the Perimeter of a Garden

Sarah has a rectangular garden that measures 8 feet in length and 5 feet in width. She wants to put a fence around her entire garden. What is the total length of the fence she needs to buy?

You can find the perimeter of a rectangle using the formula: $$P = 2(l + w)$$, where $$l$$ represents the length and $$w$$ represents the width.
