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.  

I’m not positive but i think it’s none of your buisness

Uneed to add them up 27+18+23=68
