Expert Answer:
Bond length increases with decreasing bond order. The nitrogenoxygen bond order in NO3- is less than the nitrogenoxygen bond order in NO2- (1.3 versus 1.5, respectively). Therefore, NO3- has longer nitrogenoxygen bonds than does NO2-.
For reference :
The nitrate ion has three equivalent resonance structures.

There are four NO bonding pairs distributed over three NO bonding locations.
