The reason I'm so pleased is that many people ask us to determine the area of a four or moresided property with just the length measurements, not realizing that these alone don't provide a single shape (and therefore area). We have even written an F.A.Q. article on this with a demonstration of the problem. Once you measure the diagonal's length, you can use Heron's formula to compute the area of each triangle, add them up and you'll have your total square footage (if you measure distances in feet, that is). Then divide by 43560 square feet per acre to get the acreage. Cheers,
