What is octagon ?

• A polygon of eight angles and eight sides.
• It has eight lines of reflective symmetry and rotational symmetry of order 8. A regular octagon is represented by the Schläfli symbol {8}.
• The internal angle at each vertex of a regular octagon is 135° ( radians). The central angle is 45° ( radians).

each side of house = 22 feet long

Perimeter of octagon = 8 × sides

Length of each side of house = 8 × 22 ⇒ 176 feet²

Therefore, length of each side is 176 feet ² .
