Okay. Here's the full explanation. I'll work out the numbers
on the next page,
3/4 of a 50 foot radius circle + 2 wedges of a 40 foot circle + 1 triangle - 1/2 the barn.

angles and the area. You need to find the lower angle of the triangle and
subtract from 135. That will be the angle of the wedges.
