Note Area of a Hexagon

Introduction for find the area of a hexagon

* In geometry, a hexagon is a polygon with six edges and six vertices. A regular hexagon has Schläfli symbol {6}.

* A regular hexagon has all sides of the same length, and all internal angles are 120°. The total of the internal angles of any hexagon is 720 degrees.
* A regular hexagon has 6 rotational symmetries (six lines of symmetry) and 6 reflection symmetries (rotational symmetry of order six), making up the dihedral group D6.

Example Sums for Finding Area of Hexagon Example 1:

Find the area of a regular hexagon whose side length is 9cm?

This can also help us on height in inches

Solution:

The formula to find the area of a hexagon with side length 2cm is

= 3 * square root of 3 * 9 2 / 2

= 3 * 1.732 * 81 /2

= 210.438cm 2
