I need some Geometry Help Quick

If all the interior angles are equal, they must all be  = 60°

So.....we have six equilateral triangles....and the area  of  any two triangles with the same side =  (side^2) √ (3)/ 2

So...the area  is

 (2^2 + 3^2 + 8^2) *√3 /2  =  77√3 / 2   

I have not looked much but the angles will all be 120 degrees.

Use cosine rule to find distance AE

triangle AFE and triangle DBC are congruent

so AE = BD

Area of AFE can be determined.

ABDE is a parallelogram. I am pretty sure it is a rectangle but i have not looked at it enough to be sure.

If it is a rectangle then the area is easily obtained.

That is a rough outline of some of the steps you will need to use.

Area of hexagon  ABCDEF ≈ 39.84 u²     or     Area = sqrt(3) * 23    

The answer is 15*sqrt(2).

In hexagon ABCDEF, AB = DE = 2, BC = EF = 3, and CD = AF = 8, and all the interior angles are equal.

Find the area of hexagon ABCDEF.
