Hexagon

Definitions:

  • a: Edge Length
  • U: Perimeter
  • A: Area
U a Layer 1

Perimeter of a Hexagon

The perimeter U is the length of all 6 sides.

\( {\color{blue} {U}} = 6 \times {\color{red} {a} } \)
U = Perimeter
a = Edge Length

\( {\color{red} {a} } = \frac{\color{blue} {U}}{6} \)
a = Edge Length
U = Perimeter


A a Layer 1

Area of a Hexagon

The region inside a hexagon.

\( {\color{OliveGreen} {A}} = \frac{3}{2} \times {\color{red} {a} }^{2} \times \sqrt{3} \)
A = Area
a = Edge Length

\( {\color{red} {a} } = \sqrt{ \frac{\color{OliveGreen} {A}}{ \frac{3}{2} \times \sqrt{3} } } \)
a = Edge Length
A = Area
