    Integrating the density of an elliptical plate

    Homework Statement ∫∫D√(9x2+4y2) dx dyD is the region: x2/4+y2/9=1 My understanding is that i have to integrate the function of a density to calculate the mass of plate which is ellipse. Problem is i can't and shouldn't be able to integrate this integral at my level, so am i missing some way...
