We study the contributions for the and originating from the intermediate states and in the charmless three-body decays , with , in the perturbative QCD approach. The subprocesses are introduced into the distribution amplitudes of system via the kaon electromagnetic form factors with the coefficients taken from the fitted results. The predictions of the branching fractions for the decays with the intermediate state decays into or are about of the corresponding results for the quasi-two-body decays in this work.
