You could align the edge of the object with the zero on the ruler and then read off the marking on the ruler which aligned with the other end of the object.

It depends on what object you are trying to measure. Displacement is appropriate for a medium sized, non-soluble object, of any shape. It would be pretty useless if you wanted to measure the volume of a concert hall or a needle! And it would not work for a sugar cube either. A micrometre would be appropriate for small objects with simple geometry, such as a needle or possibly a sugar cube. But is would be no use for a concert hall nor an irregular object. A ruler would be appropriate for large objects with a simple geometry such as a concert hall. But it would be no use for a needle, nor for an irregular object.

To measure a foot length you could use a ruler, a yard stick, a tape measure, or any object that you knew was precisely one foot long on a side or edge.
