The perimeter of the new m-phone is 16 inches. The phones length is 5.25 inches. What is the width of the phone

True [87]

Perimeter is all the sides added up together.
Divide 16 by 2, so that you can get just a measurement of the length and the width.

16/2 = 8

Since the length is 5.25, subtract that by 8.

8-5.25 = 2.75

The width of the phone is 2.75 inches.
