Joanne was hired by a florist to make large bows for holiday wreaths. Each roll of ribben has 20 yards. Joanne used 3 1/2 rolls of ribben to make 15 bows. How many feet of ribben did she use to make each bow?

I'm just guessing, but my answer would c. 0 to 300.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
