You need to be more clear about what it is you don't understand.
The word as accurately as possible referees to numbers. If i provide a reading of 5-10 cm that is not accurate. If i provide a reading a of 5 cm that is more accurate. If i provide a reading of 5.31495 cm that is even more accurate.
As accurately as possible means as much as you can get out of your ruler/protractor.
