All bond lengths are identical in ${\mathrm{MnO}}_4^{-}$ion as well as in ${\mathrm{MnO}}_4^{2-}$ ion separately.

All the anions are coloured diamagnetic species, having tetrahedral geometry in which all three non-axial d-orbitals are used in hybridisation of central atoms of anions.

Both ${\mathrm{K}}_2{\mathrm{CrO}}_4\&{\mathrm{K}}_2{\mathrm{MnO}}_4$ are isomorphous with ${\mathrm{K}}_2{\mathrm{SO}}_4$

${\mathrm{Cr}}_2{\mathrm{O}}_7^{2-}$ gains 6 electrons when used as an oxidizing agent in acidic medium , and has greater bridging chromium oxygen bond length as compared to terminal chromium oxygen bond length.
