    Answer:The length must be greater than 34 cm.

    Step-by-step 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.
