I put the dimensions in the familiar way we express it "Rectangular Hollow Section beam 200x100x8mm, 3m long" So that's 200mm tall, 100mm wide and 8mm wall thickness. 3metres long, obviously You could check my values against beam tables - eg. in "The Blue Book" https://www.steelforlifebluebook.co.uk/hfrhs/ec3-ukna/section-properties-dimensions-properties "200x100x8" is a commercial section. I see what you are asking about "incline". The implicit assumption for a "simple beam" - it sits on an immovable support at each end, otherwise span free space and is loaded in the middle - is that the beam is horizontal and the load is vertical, as would be the case for a mass in gravity bearing upon the beam
