The four sided, a=110.50 ft, b=165.27, c=162.18, and d=a slightly curved line of 146. ft--(adsbygoogle = window.adsbygoogle || []).push({});

(from point to point, it still seems to be 146 feet,) anyway---This from a land survey---I believe the distances of width, center point and (height) can "prove" by the angles. The people I have been talking to claim it is a parallelogram. (professionals) and told me the corners have to add to 360 degrees---I will post an image. I am confused by the math of the people I have been speaking with.
