Using an sample of $20.3\,\rm fb^{-1}$ collected at a center-of-mass energy 3.773 GeV with the BESIII detector, we report measurements of several four-body hadronic decays of mesons. All studied decay modes are dominated by Cabibbo-favoured amplitudes. The absolute branching fractions are determined to be , , , , , , and . Furthermore, significant signals are found in the decay channels involving a pair, and their fractions are determined as , , and . The branching fractions of , , and are measured for the first time, and those of , , , , and are measured with improved precision. The first uncertainties are statistical and the second are systematic.
