It depends on the type of ruler you are using. Depends if you are using a just metric unit ruler or if you are using a yard/meter stick. The measurements should be written along the edge of the ruler.
Make sure you are using the correct SI unit on the ruler.

You cannot. You cannot ensure the lines are strictly parallel using only a ruler.
There is a hole in the ruler (i.e.) circle just make the circle using that

To record measurements using a ruler, place the ruler next to the object to be measured. Ensure that the zero mark on the ruler aligns with one end of the object. Read the measurement where the other end of the object falls on the ruler and record it in the appropriate units.
The ruler measured the length of the table to be four feet.
