Quizplus · Accepted Answer

To find the amount of wiring needed to enclose the yard, we need to find the perimeter of the yard by adding up the distance around all four sides. 
Perimeter = 104ft + 65ft + 83ft + 93ft = 345ft
Therefore, the answer is (C) 345 feet. The perimeter of a rectangle is the sum of all its sides. Therefore, the total wiring needed is the perimeter of the rectangular yard. 
Perimeter = 104 + 65 + 83 + 93 = 345 feet
