Hectogon

A hectogon or hectagon is a shape with 100 sides and 100 corners.

All sides of a regular hectogon are the same length. Each corner is 176.4°. All corners added together equal 17640°.

The area of a regular hectogon of side length a is given by

${\displaystyle A=25a^{2}\cot {\frac {\pi }{100}\simeq 795.513a^{2}$
