What is the perimeter in metres of 1.5 hectares?
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.
