Jeff is using tape on the gym floor to mark sides of a rectangular volleyball court. the court is 18 meters long. it has an area of 162 square meters. each 20-meter roll of tape costs $2.79. what is the total cost for the rolls of tape that jeff needs to mark the sides of the volleyball court

a. $5.58

b. $8.37

c. $11.16

d. $13.95

First, determine the width of the court by dividing the area by the length.

width = area / length

width = 162 m²/18 m = 9 m

Then, determine the perimeter of the court by the equation

P = 2L + 2W

where L and W are length and width, respectively.

P = 2 (18m) + 2 (9m) = 54 m

Given that every 20 m roll of tape costs $2.79, and even if the court is only 54 m, Jeff still needs to buy 3 20-m roll

total cost = ($2.79) x 3 = $8.37

Thus, the answer is letter B.
