Mrs. Aster wants to plant a vegetable garden on a plot of land in the shape of a rectangle. The length of the garden is 12 feet, and the area is 96 square feet. It costs $17.31 per linear foot to install a fence. If the gate is 3 feet wide and costs $129.89, what is the total cost of the fencing for the garden?

A. $147.20
B. $597.39
C. $770.36
D. $821.29

Answer :

c. 770.36

first you find the length of garden using area=lw formula -> w=8 ft

find perimeter of garden
p= 2l + 2w -> 40 ft

subtract 3 ft for the gate
40ft -3ft= 37ft

need to find 37ft of fencing
37ft× 17.31= $640.47

add that to the price for the gate
$640.47 + $129.89 = $770.36
