millimeters centimeters meters kilometers
I gave my students this multiple choice question: New carpet is being measured for a room that is 5.5 m by 4.6 m. On a measuring tape, what is the smallest unit that is necessary to measure the room accurately for the carpet?

Only one answer is correct among these 4 choices:
- millimeters
- centimeters
- meters
- kilometers

Could you tell me which one is correct?

centimeters
