Regular Octagon Area (related to the span)


Octagon is a polygon that has eight sides.
A regular octagon is a closed figure with sides of the same length and internal angles of the same size. The internal angle at each vertex of a regular octagon is 135°. The area of a regular octagon is related by the length of the side and the length of the span of the octagon, or the second shortest diagonal.
