Answer:
at least 14 ft
Explanation:
The area of the rectangular region is the product of its length and width. We are told the area must be at least some value.
A = LW . . . . . . . . . area formula
A ≥ 217 ft² . . . . . . . . . given constraint
(15.5 ft)W ≥ 217 ft² . . . . . . substitute LW for A, use given length
W ≥ 14 ft . . . . . . . . . . divide by 15.5 ft
The possible width of the region is at least 14 feet.
