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

88-32 = 2x

56 = 2x

x = 56/2 = 28.
