Hello, what1sth1s!

I don't suppose you made a sketch.

You have two 8 x 12 walls. .They can be paneled like this.

      : - - - 12- - - - :
      *-----*-----*-----*
      |     |     |     |
      |     |     |     |
    8 |     |     |     | 8
      |     |     |     |
      |     |     |     |
      *-----*-----*-----*
         4     4     4

You have two 8 x 20 walls which can be paneled like this:

      : - - - - - - 20- - - - - - - :
      *-----*-----*-----*-----*-----*
      |     |     |     |     |     |
      |     |     |     |     |     |
    8 |     |     |     |     |     | 8
      |     |     |     |     |     |
      |     |     |     |     |     |
      *-----*-----*-----*-----*-----*
         4     4     4     4     4

Now how hard was that?
