Why could a single translation map one of the long rectangular benches onto the other long rectangular bench, but not map one short rectangular bench and flagpole onto the other short rectangular bench and flagpole?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
