Answer:
9 feet
Step-by-step explanation:
The perimeter of a rectangle is 2(l + w) = p, where l = length, w = width, and p = perimeter.
- In this case, we're given the values of the width and perimeter: 2(l + 3) = 24
- We can solve this equation algebraically!
Step 1: Distributive the 2 to the terms inside the parentheses.
Step 2: Subtract 6 from both sides.
Step 3: Divide both sides by 2.
Therefore, the length is 9 feet.
