A) Add three line segments (AD, CF, BE) to the regular hexagon.

B) The area of each triangle of the regular hexagon is 35.1 in².

C) The area of the regular hexagon is 210.6 in².

How to calculate the area of a regular hexagon

In geometry, regular hexagons are formed by six regular triangles with a common vertex. We decompose the hexagon in six equilateral triangles by adding three line segments (AD, CF, BE).The area of each triangle is found by the following equation:

A = 0.5 ·  (9 in) · (7.8 in)

A = 35.1 in²

And the area of the regular polygon is six times the former result, that is, 210.6 square inches.
