The length of a rectangle is fixed at 16 cm. What widths will make the perimeter greater than 88 cm?

Answer 1

88 - 32 = 56

56/2 = 28

Any width more than 28 cm will make the perimeter greater than 88 cm.

Answer 2

Ms. Sue's answer is correct. If you would like to see the work set in in the form of an equation,
Let x = the width
16 = length.
The perimeter is 88.
88 = x + x + 16 + 16
88 = 2x + 32
88-32 = 2x
56 = 2x
x = 56/2 = 28.
