The perimeter of a rectangle is 48 feet. If the length measures 16 feet, which is the width?

A. 5ft

B. 8ft

C. 10ft

D. 16ft

B. 8ft

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2 (l+w) where l is the length and w is the width

Substituting in the given values

48 = 2 (16+w)

Divide each side by 2

48/2 = 2/2 (16+w)

24 = 16+w

Subtract 16 from each side

24-16 = 16+w-16

8 = w
