How much fence wire do I need for 40 hectares?

To determine how much fence wire you need for 40 hectares, first find the perimeter of the area. A hectare is equivalent to 10,000 square meters, so 40 hectares is 400,000 square meters. If the shape of the area is square, the perimeter would be approximately 2,528 meters (since the side length is about 632 meters). Therefore, you'll need around 2,528 meters of fence wire, but adjust this figure based on the actual shape of your land and any gates or openings.
