In hexagon ABCDEF, AB = DE = 2, BC = EF = 4, CD = FA = 6, and all the interior angles are equal. Find the area of hexagon ABCDEF.

I cannot find any theorems or anything for that area...please explain...AND THX

Good. You can read.

hi

Don't know if this is the quickest way but it should work.

Box in the hexagon as shown in my diagram. (All the angles are 120)

Use trig to calculate the length and width of the box.

Calculate its area and subtract the areas of the unwanted triangles.

Thanks guys! actually you don't have use trig, the triangles are 30-60-90, so sides are 2:1:sqrt(3)

Thanks a ton! wouldn't have got without ya!

I got that too bobbym.
