In the case of a regular hexagon the formula can be derived by
thinking of six equilateral triangles meeting at a point.

Let r = the side of the triangle; then the area of each triangle is
(1/2)r^2*sin(pi/3) = (1/2)r^2*sqrt(3)/2 = (1/4)r^2*sqrt(3).

For six such triangles the area = (3/2)r^2*sqrt(3)

I've tried to work out the area of a hexagon with each side being 8
feet.  I was working with the idea of 6 equilateral triangles. The
answer I came up with was 96 sq.ft. Is this the right answer? Thanks

The area of one triangle is (1/2)*64*sin(60)

The area of six triangles is 3*64*sin(60) = 166.277 sq.ft
