Answer:
i think its 225 but i can still be wrong
so if 5.5 is in meter let change it to cm because the question want us to give the answer in cm.


now we multiply 5.5 times 100 which is equal to 550.
next we subtract 550 - 220= 330.
finally, the difference between a teacher and student is 330cm .meaning the teacher's desk is 330 cm longer or taller than the student.
