Abstract: The Steiner formula and the mixture area formula given by Mller were expressed under the l-parameter closed planar homothetic motions in the complex sense.Also,using the generalization of Steiner formula,the result of Holditch theorem for homothetic motions is got.In the case of the homothetic scale h≡l the results given by Mller are obtained as aspecial case.-
