Octágono

The perimeter U is the length of all 8 sides.

${\color{blue} {U}} = 8 \times {\color{red} {a} }$

U = Square alcance

a = Borde longitud

${\color{red} {a} } = \frac{\color{blue} {U}}{8}$

a = Borde longitud

U = Square alcance

The region inside an ocatagon.

${\color{OliveGreen} {A}} = 2 \times \left( 1 + \sqrt{2} \right) \times {\color{red} {a} }^{2}$

A = Área

a = Borde longitud

${\color{red} {a} } = \sqrt{ \frac{\color{OliveGreen} {A}}{ 2 \times \left( 1 + \sqrt{2} \right) } }$

a = Borde longitud

A = Área
