There are many different shaped properties with different areas that have exactly these side lengths. There is more information on this at http://mathcentral.uregina.ca/QQ/database/QQ.09.03/dave1.html Harley Greg wrote back.
Greg, I drew a diagram of your property and labeled the corners. Unfortunately I didn't ask you to tell me which diagonal you measured so, for the moment, I chose one.
Dimensions in feet The property is divided into two triangles and I can find the area of these triangles using Heron's Formula. I used Heron's formula and found
If the 52.6 ft diagonal joins B and D the I get
It is surprising they are so close,
