Using pdf file taking area and giving a pitch to it, but with degrees & metric system?

I'm no good at this but my idea would be to calculate the two areas separately A and B and add the results?Rooftop.png

I assume, but i need someone to confirm:



=AREA / SIN((ROOF PITCH DEGREES)*PI()/180) - To get pitched area - Not sure if this is correct formula, but it seemed it is


=AREA / COS((ROOF PITCH DEGREES)*PI()/180) - To get Floor plan area into pitched area ( i know that works )

If memory serves correctly

Projected area (includes overhangs) * (rise^2+run^2)^0.5
ie the area * hypotenuse

If calculating roofing material add for waste and ridge.

I'm talking about converting Flat area into pitch.


Same way as taking Floor plan area at pitch 0 degrees,

lets say 100 sqm floor plan - now i give it a 35 degree pitch, answer will be: 122.077 square meters


Now same way im trying to make it work out for elevation views, if on elevation i get area 75 square meter on 0 pitch, by giving a 35 degrees it should be 91.55 square meters.


I kind of think it's correct formula, but just need to clarify.
