The regular octagon will consist of 8 congruent isosceles triangles each having equal angles of 67.5 degrees and an apex angle of 45 degrees.

Equal sides are: square root of 309.019336*2/sin(45)*8 = 10.45250372 cm

Base length: 10.45250372*sin(45)/sin(67.5) = 8 cm

Perimeter: 8*8 = 64 cm

A regular octagon with sides of length 11 and an apothem of length 8.85 has an area of what?

An apothem of a regular polygon is a segment from its center to the midpoint of a side. You can use the apothem to find the area of a regular polygon using this formula: A = pa/2 where p is the perimeter of the figure and a is the apothem. For a regular octagon with side length 11, the perimeter p = 8(11) = 88. So the area would be A = 88(8.85)/2 = 389.4 square units.
