The area of an octagon is 14. Calculate side, perimeter

s = | √2(1+√2) |

√A |

s = | √2(2.1) |

√14 |

s = | √4.2 |

√14 |

s = | 2.6 |

3.9 |

s = 0.72

P = 8 x side

P = 8 x 0.72

P =

Interior Angle Sum = (sides - 2) x 180°

Interior Angle Sum = (8 - 2) x 180°

Interior Angle Sum = 6 x 180°

Interior Angle sum = 1080°

Diagonals = | n(n - 3) |

2 |

Diagonals = | 8(8 - 3) |

Diagonals =

1 vertex Diagonals = n - 3

1 vertex Diagonals = 8 - 3

1 vertex Diagonals =

Triangles = N - 2

Triangles = 8 - 2

Triangles =
