You should have an idea of the upper limit of your range if its not given(use logic). Than take atleast SIX readings at regular intervals within that range.
So if they ask l>=20cm and you have a half-meter rule(or whatever) than you take the readings for the following, 20cm, 25, 30, 40, , 45, 50. If you want to be extra thorough, you can take 35 as well as that will give a nice range of regular intervals but six should be enough in most cases.

If there is no upper limit mentioned just take readings t sensible intervals. 20, 25, 30, 35, 40, 50. min. of six readings are required for most questions.
