Since Bond length is inversely proportional to bond order , and bond order depends on number of bonds, here as CO will have triple bonds, CO2 will have two double bonds(linear structure with carbon as central atom O=C=O) however in case of CO3^-2 the bond character lies between single and double bond due to resonance.

in co2 there is more repulsion so more is the bond length try to link bond length with repulsion and geometry

Since Bond length is inversely proportional to bond order , and bond order depends on number of bonds, here as CO will have triple bonds, CO2 will have two double bonds(linear structure with carbon as central atom O=C=O) however in case of CO3^-2 the bond character lies between single and double bond due to resonance.

Hence bond length order will be CO3^-2>CO2 >CO.

Hence bond length order will be CO3^-2>CO2 >CO.

Note: We can also compare bond length in terms of value's of bond order CO3^-2(B.O=1.33)>CO2(B.O=2) >CO(B.O=3.5
