Hello,
The nonagon, polygon with 9 sides, can be divided in 9 triangles which area is
a*c/2
a is the apothem et c the side
Center's angle is 360°/9=40°
as a/14=cos 20°, and (c/2)/14=sin 20°
a*c/2=14*14*sin 20°*cos 20°=14*7*sin40°=98*sin 40°=62,993185...
Area of the nonagon is 9*98*sin 40°=882*sin 40°=566,93867... (in²)
