What I would do is divide it into triangles and find the area of those. If it's not to scale or somthing, find the formula online.
I hope this helped.
You don't need to find the forumula online.
Area of a triangle is 1/2 * base * perpendicular height
It depends what lengths or angles you are given as to how you go about doing this.
Are you talking about a regular hexagon? What info do you have?
Re: Area of hexagon
-----------------------------------------------------------------------------------------------------------------
Let's think about this for just a second. A hexagon is just composed of 6 equilateral triangles. Then the area of one of these triangles is just (1/2)s2sin(60°) = (1/2)s2(√(3)/2) = (1/4)s2(√(3), where s is the side length of the hexagon. And since we have 6 of these triangles, then the total area is just 6* (1/4)s2(√(3)=
(3√(3))/2*s2
