Answer:
8.5 feet
Step-by-step explanation:
the perimeter is the amount of units around an onject
so if a rectangle has two pairs of equal sides and one side is provided (14 feet)
multiply 14 by 2
subtract the product (28) from the given total (45) and you get 17
then you divide 17 by 2
(17 being the the sum of two equal sides)
8.5 feet is the outcome
