Sir, I got selected Room area too, use getSelectedItems.

How can i get width of furniture which selected (as in same way we can get selected furniture width) but which is inside that selected room.
When i get those values separately, it gives answer. But as together, there's no answer.
can u tell me, how can i do it.
