Regular Hexagon

Side Length

Math check: area = (3 sqrt(3) / 2) s^2, perimeter = 6s

Result

Enter a side length to compute the hexagon properties.

Formulas

A = (3 sqrt(3) / 2) s^2

P = 6s

a = (sqrt(3) / 2) s

R = s

If the side length is 5, the perimeter is 30 and the area is about 64.9519.

The circumradius equals the side length, so it is 5.

A regular hexagon can be decomposed into six equilateral triangles of side s.
