How to use this table
Find the row closest to your side length and read across to the area. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Dodecagon Area Calculator for a precise answer.
Need a value that is not in the table? — the Dodecagon Area Calculator does it instantly, for free, with the formula and a worked example built in.
