The Area of a Hendecagon calculator computes the area of a regular hendecagon, a polygon with 11 equal sides of length (s).
INSTRUCTIONS: Choose units and enter the following:
Area of a Hendecagon (A): The area (A) is computed in square meters. However, the area can be automatically converted to many other area units (e.g. acres) via the pull-down menu.
For the CLICK HERE.shaped column,
A regular hendecagon has eleven equal sides and equal angles. The formula for the area of a hendecagon is as follows:
where s is the length of a side.
A regular hendecagon has eleven equal sides and equal angles. For computational performance, `11/4 * cot(pi/11)` is approximated to be 9.365639907.
