6 . Measure distances.

To measure distances we have different measurement devices and methods depending on the distance and the accuracy needed. For household use we use the tape-measure and the ruler measuring in centimetres and milllimetres.
 

Measure the distance between the points with the ruler, type the corresponding number below. Use the suitable unit (centimetres or millimetres). After typing the number hit Enter.
Do it successively from top to bottom. If your answer is correct, this number will appear. If it isn't, it won't appear.

You can move the rulers from their ends, one after the other.
