Final answer:
To calculate the cost of a new boundary line for a volleyball court, you multiply the perimeter of the court (52 yards) by the cost of the rope per yard ($1.35), resulting in a total cost of $70.20.
Step-by-step explanation:
The question is about calculating the cost of a new boundary line for a beach volleyball court, given the dimensions of the court and the price per yard of the rope. First, we need to find the perimeter of the volleyball court. The court is 9 yards wide and 17 yards long, so the perimeter is twice the sum of the width and length: 2 × (9 + 17) = 2 × 26 = 52 yards. The rope costs $1.35 per yard. Therefore, the total cost for the boundary line would be 52 yards × $1.35 per yard.
Now, we will do the multiplication: 52 yards × $1.35 per yard = $70.20. So the cost to buy a new boundary line for the court is $70.20.
