dA is not a derivative, but rather represents the 2d area element dxdy.

that would give two dimensions; what is the third?

My guess: there isn't a third dimension to integrate over, unless one were to rewrite the integral to be of the function f(x,y,z) = 1; and change the domain to also include z.

Whenever you are faced with a problem to solve start trying to solve it with the methods at hand.
1, You surely know how to do a goolge-search, so try a search for something like "double-integral matlab", and look for some of the answers that seems relevant.
2, When using matlab you should learn about using the commands lookfor and help, try something like this:
help lookfor
3, after that you should be able to start to zoom in on the integral functions. Now you're ready to read the help and documentation of integral2.
