Urgent help with geometry problem

Hi, I'm new to the forum and I need help with this geometry problem.

http://i104.photobucket.com/albums/m...thsProblem.jpg

It is meant to be a layout of a car park constructed out of a normal hexagon and a normal rectangle. So all sides of the hexagon are 9m.

I need to find the following:

1.

Find the perimeter. This one is simple enough.

2.

If A is the midpoint of DC, find the size of the angle y.

3.

Find the length of side x.

4.

Calculate the area of the triangle ABC.

5.

Calculate the area of the whole shape.

I'm mostly just unsure of where to start and what methods to use. If anyone could show me how to work through these questions or point me in the right direction that would be greatly appreciated.

Thanks in advance. :D

EDIT: I guess this should probably have gone in the Trig forum.
