What is the perimeter in metres of 1.5 hectares?

Answer 1

The area does not uniquely determine the linear dimensions of the boundary. The same area could be covered by many different shapes, with different dimensions. 1.5 hectares is 15,000 square meters. If the field is square, then the length of each side is about 122.5 meters, and the perimeter is about 489.9 meters. If the field is a circle, then its diameter is about 138.2 meters, and its perimeter (circumference) is about 434 meters. If the field is a triangle with 3 equal sides, then the side is about 186 meters, and the perimeter is about 558.4 meters. It could also be a rectangle measuring 150 by 100 (perimeter = 500), or 15 by 1,000 (perimeter = 2,030), or 5 by 3,000 (perimeter = 6,010), or many other choices. If you want to buy a piece of land and there's somebody willing to sell it to you by perimeter, buy a circle. It's the perimeter that covers the most area, and that means the most wheat or soybeans. Of course it also means the most property tax, and if you build on it, the most lawn to mow.
