Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

How do you determine the square footage for a pie shaped lot.

You need to specify the angles in the corners as well as the lengths of the sides. Alternatively, you can specify both the length and the bearing angle of each of the four sides (usually available from the deed) and calculate it.

The minimum is to know the four sides and any one angle (you have to know which sides the angle is between). You can calculate the diagonal opposite the angle using the law of cosines. Now the lot is divided into two triangles, each with all three sides known, and the area is easily calculated using Heron's formula, or other methods.
