CALCULATING ACREAGE ON UNEQUAL SIDES

I have a piece of property that is 315 ft 8 inches, 165 ft, 236 ft, and 128 ft 2 in.  How many acres is that?  And how do I calculate it?
Thanks!

Not enough information.  You need to know something about the shape of the property.
Do you know the angles at the corners?   Are any of the sides parallel?

My diagram 3 is a little confusing. The diagonal line, which I labelled S, is NOT the same s used in heron's formula, which is the semi-perimeter of a scalene triangle. Don't confuse the two!

AWESOME!  You folks are amazing.  Attached is the actual diagram.  I have an added anomaly in that the front of the shape is slightly curved.

<DO NOT ACCEPT THIS FOR POINTS>

from that diagram, and assuming that the angles at the base are both 90 degrees, the area is close to 45516.90 sq feet

165.00 * 236.06 = 38949.9
1/2 * 165 * 79.60 = 6567

total = 45516.9 sq feet = 1.04 acres  

that may be slightly on the low side, as the street boundary has a small curvature, which would incread the total area by perhaps a couple of sq feet.

Thanks Arthur for the final answer.  And thanks to all for helping me understand how to do it in the future!!
ignoring the curvature, 165 * (236.06+315.66)/2 = 45516.9


Ohh .. the two triangle solution is much more elegant.

Thanks!
