Hexagon Formulas

1. Area of Regular Hexagon Formula

Area = 3 \sqrt 3 \times s 2

Area is 3√3 times the square of side length (s).

Perimeter = 6 \times s

Perimeter is 6 times the side length (s).

a = \frac{s \times \sqrt 3}{2}

Apothem is side length (s) times √3 divided by 2.

θ = 120

Each interior angle is 120°.

Exterior Angle = 360 / 6

Each exterior angle is 60°.

s = \sqrt{\frac{Area}{3 \sqrt 3}}

Calculate side length using area.
