compute ∫∫ 1da where D is the region in the xy-plane given by x^2+y^2=R^2?

Your ∫∫ 1da is a double integral having only one differential. Region D is a circle of radius R, but there is no given relation between D and the integral.
If da is dxdy, a differential of area in the x-y plane, and if region D defines the limits of the integral, then the result of the integral is simply the area of D.
