first get the perimeter of the yard using the formula for the perimeter of a rectangle,that is  P = 2L + 2W, so we will have 2(25) + 2(18)...the answer is 86 ft.

After finding the perimeter, multiply it by the cost of the fence per foot.....so we have

(86)(4.30) = $369.80 will be the cost of the fence...
