What is the perimeter of the rectangle 14 feet?

Correct answer: 36. Explanation: Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.

What is the formula to find the area of a rectangle?
