If a rectangle has a perimeter of 36 feet, and it’s 4-feet wide, what’s its area?

  1. 56 square feet
  2. 128 square feet
  3. 112 square feet
  4. 16 square feet

Answer(s): A

Explanation:

To find area, multiply length times width (A = lw). To determine the length, subtract two times the width from the perimeter: 36 – 2(4) = 36 – 8 = 28.
Then divide the remainder by 2 to determine the length of one side: 28 ÷ 2 = 14. Then multiply length times width to determine the area: 14 × 4 = 56.
