# Hexagon Side = 20

## Enter hexagon info

<-- Enter Area or Perimeter or Side

Hexagon has side length (s) of 20
calculate the Perimeter (P) and Area (A)

## Calculate Perimeter:

P = 6 x s
P = 6 x 20
P = 120
 A  = 3√3s2 2

 A  = 3√3(202) 2

 A  = 3√3(400) 2

 A  = 2078.46 2

## Calculate Area (A):

 A  = 3√3s2 2

 A  = 3√3(202) 2

 A  = 3√3(400) 2

 A  = 2078.46 2

A = 1039.2304845413

## Calculate Sum of the Interior Angles:

Interior Angle Sum = (sides - 2) x 180°
Interior Angle Sum = (6 - 2) x 180°
Interior Angle Sum = 4 x 180°
Interior Angle sum = 720°

## Calculate polygon diagonals

 Diagonals  = n(n - 3) 2

 Diagonals  = 6(6 - 3) 2

 Diagonals  = 6(3) 2

 Diagonals  = 18 2

Diagonals = 9

## Calculate 1 vertex diagonals:

1 vertex Diagonals = n - 3
1 vertex Diagonals = 6 - 3
1 vertex Diagonals = 3

## Calculate triangles from one vertex:

Triangles = N - 2
Triangles = 6 - 2
Triangles = 4

## Other Properties:

Sides (Edges) = 6
Faces = 1
Vertices = 6

s = 20
P = 120
A = 1039.2304845413
Interior Angle sum = 720°
Diagonals = 9
1 vertex Diagonals = 3
Triangles = 4
Sides (Edges) = 6
Faces = 1
Vertices = 6
