3x +4y+175x-2y=11

4y-2y+175x+3x=11

2y+178x=11

2y=11-178x

y=\frac{11-178x}{2}

y=-89x+\frac{11}{2}

178x=-2y+11

x=\frac{-2y+11}{178}

x=\frac{-1}{89} y+\frac{11}{178}

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

B) The area of each triangle of the <em>regular</em> hexagon is 35.1 in².

C) The area of the <em>regular</em> hexagon is 210.6 in².

<h3>How to calculate the area of a regular hexagon</h3>

In geometry, regular hexagons are formed by six <em>regular</em> triangles with a common vertex. We decompose the hexagon in six <em>equilateral</em> triangles by adding three <em>line</em> 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 <em>regular</em> polygon is six times the former result, that is, 210.6 square inches.
