    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.
