The two highlighted polygons in the image are pieces of vacated right-of-way. I need to determine the amount of acreage of each of those polygons to assign to Lot 2R and to Lot 3. The dimension annotations are true per the recorded surveys of the land. However, the actual length of the lines when measured in ArcMap do not match the surveyed dimensions. That also means that the stated area in the parcel attributes does not match the acreage given on the survey. (Our fabric is a little wonky in some areas, nobody's perfect!)
Without re-teaching myself high school geometry and calculating by hand, which seems like it would be a pain in the butt to do with those curves, what would be the easiest way to utilize ArcMap to get the acreage I need here?
