Formula For Octagon Sides Length. The formula for the area of a regular octagon is:a = 2 (1+ sqrt(2)) s**2 , ora = 4.8284 s**2where a= the area of the octagon, ands is the length of one side s**2 indicates s squared or s times s For example, here’s how you’d find the area of eightplu in the figure below given that it’s a regular octagon with sides of length 6.
A = 2 * a² * ( 1 + √2 ) rc= a / 2 * √4 + 2 * √2. The perimeter of the octagon is the length of the sides or boundaries of the octagon, which forms a closed shape. In my diagram the diameter is d and the side length is s.
Perimeter = length of 8 sides.
A regular octagon is a closed figure with sides of the same length and internal angles of the same size. All eight sides of an octagon are equal in length, and all eight angles are equal in size. The formula for the area of a regular octagon which has 8 equal sides and all its interior angles are equal to 135°, is given by: Octagon is a polygon with eight straight sides and angles, a geometric shape on the two dimensional plane.
