Answer:

  width ≥ 7 cm

Step-by-step explanation:

The perimeter formula is ...

  P = 2(L +W)

We have P ≥ 32 and L = 9. We want to find W. (Dimensions are cm.)

  2(9 +W) ≥ 32 . . . . substitute for P and L

  2W ≥ 14 . . . . . . . subtract 18 and simplify

  W ≥ 7 . . . . . . . . . divide by 2

Possible widths are at least 7 cm.
