The of an heptagon is
  

The area of an heptagon = 5

Calculate side, perimeter

Calculate side:

A = 7/4s2cot(180°/7)

s2  =  4A
  7cot(180°/7)

s2  =  4 x 5
  7cot(25.714285714286)

s2  =  20
  7 x 2.0765213992964

s2  =  20
  14.535649795075

s2 = 1.3759274805022

s = √1.3759274805022

s = 1.1729993523025

Calculate Perimeter:

P = 7 x side

P = 7 x 1.1729993523025

P = 8.2109954661178

Calculate Sum of the Interior Angles:

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

Interior Angle Sum = (7 - 2) x 180°

Interior Angle Sum = 5 x 180°

Interior Angle sum = 900°

Calculate polygon diagonals

Diagonals  =  n(n - 3)
  2

Diagonals  =  7(7 - 3)
  2

Diagonals  =  7(4)
  2

Diagonals  =  28
  2

Diagonals = 14

Calculate 1 vertex diagonals:

1 vertex Diagonals = n - 3

1 vertex Diagonals = 7 - 3

1 vertex Diagonals = 4

Calculate triangles from one vertex:

Triangles = N - 2

Triangles = 7 - 2

Triangles = 5

Other Properties:

Sides (Edges) = 7

Faces = 1

Vertices = 7
