Parallel dielectrics in a capacitor

If three dielectric of slabs of same thickness, but different areas of  cross section A1, A2 & A3 , dielectric constants K1, K2 & K3 are placed between the plates of a parallel plate capacitor as shown, then the combination behaves as different dielectrics dividing the plate area are considered as capacitors connected parallel.

Capacitance of this is given by

Cnet = C1 + C2 + C3
