Question

Use the formula for the area of a rectangle A = lw to answer the question.

A rectangle has a length of n units. Its width is 8 units more than its length. What is the area of the rectangle?

A.
2 + 8n

B.
n(n – 8)

C.
n(n + 8)

D.
2n + 8

Answer 1

A = lw

A = n(n + 8)

The answer will be C

Answer 2

A = lw
Length = n units
Width = n + 8

Now substitute back into equation:
A = n(n + 8)

The answer is C. n(n + 8). Hope this helped!
