Regular triacontadigon
All sides of a regular triacontadigon are the same length. Each corner is 1683⁄4°. All corners added together equal 5400°.
Area
The amount of space a regular triacontadigon takes up is
- [math]\displaystyle{ \text{Area} = 8a^2 \left(1+ \sqrt{2} + \sqrt{4 +2 \sqrt{2} } +\sqrt{8 +4 \sqrt{2} +2 \sqrt{20 +14 \sqrt{2} } }\right). }[/math]
a is the length of one of its sides.
