---------
find the area of a regular nonagon whose sides measure 3 millimeter.
--------

central angle of the nonagon, degrees

The nonagon's side for one of these sections forms a base of a triangle. From center of the nonagon to midpoint of the base, is "height" of triangle. This height: for height h;

Area of one of these triangles:

The nonagon contains nine of these triangles:
Area of the entire nonagon:
