Answer:The length must be greater than 34 cm.

Explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

The width of a rectangle is fixed at 15cm. Let the length of the rectangle be represented by L. Therefore

2(15 + L) > 88

30 + 2L > 88

2L > 88 - 20

2L > 68

L > 68/2

L > 34 cm

So the length of the rectangle can be 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm. It goes on.
