How much barbedwire will you need for 20 acres?

Answer 1

The least possible length of fence that can enclose 20 acres is 3,308.75 ft.

That's if the field is circular.

If the field is square, then it takes 3,733.5 ft.

If it's a rectangle ... straight sides but not a square ... then the perimeter can be

anything more than 3,733.5 ft, depending on the shape of the rectangle. The area

doesn't tell you what the perimeter has to be.
