n-gons
in hexagon ABCDEF,AB=ED=2 ,AF=CD=6 ,BC=EF=4 , and all the interior angles are equal. Find the area of hexagon ABCDE.
I see you have graph paper.
You must be plotting something

Re: n-gons
I am not getting it, if all the interior angles are equal then aren't all the sides supposed to be equal too?

Did you try drawing the given problem in GG?

Maybe we can break it up into small triangles and then use Heron's Formula?

Re: n-gons
No. But I know that it is possible.
Another example would be if you a regular hexagon and just stretch out two of its sides which are parallel.

Re: n-gons
Yes. Good Example. Thats what has been done here. A simpler example is a rectangle

The answer is close to 38.12122672100419. Isn't it?

Hi;
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Geogebra, geogebra, it is the man. If it can't do it nobody can. Yay geogebra!

Re: n-gons
I agree with bobbym's answer exactly.
I have decided to hide my comment about a possible method below.
It would be interesting to know how Agnishom got an answer that is very nearly
correct but slightly out. (Assuming of course that bobbym's was right - I think it is.)
