The width of a rectangle is y feet long. The rectangle is 4 feet longer than it is wide. What is the area of the rectangle?

Question

Which expression represents the area?

a. y(y + 4) sq ft

b. y + 4 sq ft

c. 4y sq ft

Answer 1

The area of a rectangle is the height multiplied by width. So for the rectangle in question, we can say that the width is y, and since the other side (length) is 4 feet longer, we can call that y + 4. Now, we multiply the terms to give us our answer of y(y + 4) sq ft.
