Quandaries & Queries

Question from Jim, a student:

"The end of a swimming pool is a rectangle inclined 45° to the horizontal.
The edge at the surface is 12 feet long and the submerged edge is 10 feet long.

Could you draw a diagram for me ? I don't understand the Problem.
Thanks

Hi Jim,

I'm not sure I understand either but here is a guess. I am going to assume that the other end of the pool is vertical. In this case a cross-section would look like
