Final answer:
To find the unit price of the fence per foot for Leanne's puppy play area, we calculate the total perimeter of the rectangle using the formula (P = 2l + 2w) and then divide the total cost by the perimeter. The calculation shows that the unit price is $18 per foot.
Step-by-step explanation:
To find the unit price of the fence per foot for the puppy play area, we first need to calculate the total perimeter of the rectangle. The formula for the perimeter, P, of a rectangle is P = 2l + 2w, where l is the length and w is the width of the rectangle.
In Leanne's case, the length (l) is 25 feet, and the width (w) is 15 feet. So, the total perimeter will be:
P = 2(25 feet) + 2(15 feet) = 50 feet + 30 feet = 80 feet.
Now that we have the perimeter, we can calculate the unit price of the fence per foot by dividing the total cost by the total perimeter:
Unit Price = Total Cost / Perimeter
Unit Price = $1,440 / 80 feet = $18 per foot.
Therefore, the unit price of the fence per foot is $18.
