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

88  32 = 56
56/2 = 28
Any width more than 28 cm will make the perimeter greater than 88 cm.

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
8832 = 2x
56 = 2x
x = 56/2 = 28.
