Based on your numbers, I assume you're defining "scope" as 2.40:1 (not 2.35:1).
If your height is 43", that would make your width 103" to get a 2.40:1 screen.
103 / 43 = 2.4 (rounded)
Do you remember your Pythagorean Theorem? A squared + B squared = C squared. This would give you a diagonal of 112".
So, if you're projecting a 16:9 Blu-ray to fill the full width of the frame, the image will be 103" wide by 58" tall. (103 / 58 = 1.78)
The difference between 58 and 43 is 15, which means letterbox bars of 7.5 inches each above and below the screen.
Again, all of these numbers are rounded, so the exact amount may be slightly different, but that's approximately what you should expect.
