The perimeter of a rectangle is 40 feet. If the length is 15 feet, 6 inches; what is the width

4 feet 6 inches

Step-by-step explanation:

P=2 (l+w) [the addition of all sides of the rectangle]

P = 40'

L = 15'6"

So, 40' = 2 (15'6' + w)

40' = 31' + 2w

9' = 2w

4'6" = w

If it's easier you can break it change feet into inches and then change back to feet.
