Leanne is getting a puppy. Her parents are building a play area to give the puppy a place to run. The play area will be in the shape of a rectangle with length of 25 feet and a width of 15 feet.

If the total cost of the fence is $1,440, what is the unit price of the fence per foot?

P = 2L + 2W

P = 2(25) + 2(15)
P = 50 + 30
P = 80 feet

1440 / 80 = _$______ per foot

2,3

To find the unit price of the fence per foot, we need to divide the total cost of the fence by the total length of the fence.

Step 1: Calculate the total length of the fence.
Since the play area is in the shape of a rectangle, we need to calculate the perimeter of a rectangle, which is the sum of all its sides.
Perimeter = 2(length + width)
Perimeter = 2(25 + 15)
Perimeter = 2(40)
Perimeter = 80 feet

Step 2: Calculate the unit price of the fence per foot.
Unit Price = Total Cost / Total Length
Unit Price = $1,440 / 80
Unit Price = $18

So, the unit price of the fence per foot is $18.
