The side of an decagon is 6

Calculate perimeter, area

Calculate Perimeter:

P = 10 x side

P = 10 x 6

P = 60

Calculate Area:

A = 5/2s2√5 + 2√5

A = 2.5(6)2(3.0776835371753)

A = 2.5(36)(3.0776835371753)

A = 276.99151834577

Calculate Sum of the Interior Angles:

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

Interior Angle Sum = (10 - 2) x 180°

Interior Angle Sum = 8 x 180°

Interior Angle sum = 1440°

Calculate decagon diagonals

Diagonals =	n(n - 3)
	2

Diagonals =	10(10 - 3)
	2

Diagonals =	10(7)
	2

Diagonals =	70
	2

Diagonals = 35

Calculate diagonals from 1 vertex:

1 vertex Diagonals = n - 3

1 vertex Diagonals = 10 - 3

1 vertex Diagonals = 7

Calculate number of Δ from 1 vertex:

Triangles = N - 2

Triangles = 10 - 2

Triangles = 8

Other Properties:

Sides (Edges) = 10

Faces = 1

Vertices = 10

s = 6
P = 60
A = 276.99151834577
Sides (Edges) = 10
Faces = 1
Vertices = 10

What is the Answer?

s = 6
P = 60
A = 276.99151834577
Sides (Edges) = 10
Faces = 1
Vertices = 10
