The **Area of Hexagon** calculator computes the area of a regular Hexagon.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**s**) Side Length

**Area of the Hexagon (A):** The calculator returns the area in square meters. However, this can be automatically converted to compatible units via the pull-down menu.

A regular hexagon is a six sided polygon where all of the sides are the same length (**s**) and all interior angles are the same (see the diagram). The formula for the area of a hexagon is:

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

where:

- A is the area of the hexagon
- s is the length of one side of the regular hexagon

Hexagons appear in mathematics and in nature (e.g. honey comb of honey bees). The volcanic columns at the Giant's Causeway in North Ireland have regular shapes including regular hexagons.

Giant's Causeway's hexagons: Using this equation and the fact that the shoe in the picture is approximately 12" long and that the side of the hexagon is approximately the length of the shoe, the AREA of these regular hexagons is 2.5 ft^{2}.

Hexagons were also used by NASA in the James Webb Space Telescope.

The side of each JWST is approximately 0.737 meters. Use the sum of hexagon areas (CLICK HERE) to compute the total area of the 18 hexagon mirrors. The primary mirror of the Hubble Space Telescope is 2.4 meters in diameter. Use the area of a circle calculator (CLICK HERE) to compute the area of the Hubble Space Telescope primary mirror.

A **regular polygon** is a geometric shape with three or more straight sides where every side is the same length and every angle between connecting sides are the same angle. Because of the symmetry of the regular polygon, all the vertices of the polygon can be constructed to touch a circle in which the regular polygon is inscribed and all the chords that are polygon sides will then obviously be of equal length . Likewise, because of the regular polygon's symmetry, a circle constructed to be inscribed in a regular polygon and touching the polygon will touch the regular polygon at the midpoint of the polygon side. As shown in the pictures, Figure 1 and Figure 2, lines from the regular polygon's vertices to the circle's center form n isosceles triangles of equal area.

The names of polygons vary based on the number of sides as follows:

- triangle - 3 sides
- square - 4 sides
- pentagon - 5 sides
- hexagon - 6 sides
- heptagon - 7 sides
- octagon - 8 sides
- nonagon - 9 sides
- decagon - 10 sides
- hendecagon - 11 sides
- dodecagon - 12 sides
