Hi All,
I have a deceptively simple problem. I need to create a polygon with a fixed area and can't figure out any way to do this other than trial and error. Please see the example below. I'm tasked with creating a poly of 15,000 m². The NW line is fixed, NE and SW lines are fixed to the NW line and able to grow and shrink the SE line.

Because the NE and SW lines have different bearings its not a simple math problem. Below is a trial and error. One too small (11,358) and one too big (17,332) so obviously the magic 15,000 is inbetween.

My question is whats the best way to solve this problem? It seems to me that it could be done with software like Pro but a good search hasn't found anything. Any suggestions?
Thanks in advance.
Cheers,
James
