Integral of a bivariate function

For a given bivariate function I want to calculate the integral of the function over an arbitrary compact region A, for instance over A={(x,y)| f(x,y)=c} for some constant c. The function is smooth and in my application it is the joint density of two continuous random variables. I wonder if this can be done in Mathematica and in that case how. Otherwise I'd appreciate any pointer to other programs which can be used for this.
