It might be a square, a rectangle, a circle, a triangle or some irregular shape. The distance around a 5 acre property depends on the shape, not just the area. If this property is a square then each side is of length 466.7 feet and would require 4 × 466.7 = 1,866.8 feet of fencing. It might me a mile long and 41.25 feet wide and in this case the amount of fencing needed is 10,642.5 feet. Can you tell us the shape? Harley
