The width of a rectangle is 1/3 of its length. What is the area if the length is 15 feet?

A) 75 square feet

B) 5 square feet

C) 20 square feet

D) 40 square feet

Width = 5

Length = 15

This is how I found the width:

Width = 1/3 x 15. This is the same as 15/3. 15/3=5

Now just plug into the equation to find area:

Area = Length x Width

Area = 15 x 5

Area = 75 square feet

Answer: A) 75 square feet
