Compute area and get centroid area of surfaces sorted in different layers

Good afternoon,

I have a rhino model with several surfaces sorted in different layers according to their types.
i would like to get a grasshopper programm that would allow me to get surfaces (+centroïdes) of each surfaces and to extract it in an excel in a table sorted likewise the layers

I am very beginner in grasshopper.

Could you show me some leads to do so ?

Many thanks in advance
