The regular 16 sided polygon will consist of 16 congruent isosceles triangles with equal sides of 5.125830895 cm by using the sine rule with equal base angles of 78.75 degrees and an apex angle of 22.5 degrees opposite side of 2 cm.
Area of polygon: 0.5*5.125830895^2 *sin(22.5)*16 = 80.43743186 square cm
