$ 27.50

Total length required #L# = 2 lengths of 24 inches + 2 lengths of 36 inches (rectangle has opposite sides of equal length).

write this as an equation

#L = 2*24 + 2*36# inches

# = 120 in

but we are given the price per foot, so we need to find the length in feet
we know there are 12 in per foot, so divide 120 by 12 to get feet

#L=120/12 =10# ft

multiply by price per foot to get price

Price #= 10cancel(ft) * 2.75$/cancel(ft) = 27.5 dollars#

= $ 27.50
