The area of a rectangle is 16 square feet. Its length is 8 feet. The perimeter of the rectangle is?
Explanation
The area of a rectangle is length × width:
Area = length × width
16 = 8 × width
Divide both sides by 8:
width = 2
The perimeter of a rectangle is 2 × (length + width):
Perimeter = 2 × (8 + 2)
= 2 × 10
= 20
