The act, process, or art of measuring.

Measurement of geometric quantities.

The act, art, or process of measuring; specifically, the act or art of determining length, area, volume, content, etc., by measurement and computation: as, the rules of mensuration; the mensuration of surfaces and solids.

The act, process, or art, of measuring.

That branch of applied geometry which gives rules for finding the length of lines, the areas of surfaces, or the volumes of solids, from certain simple data of lines and angles.

The branch of mathematics that deals with measurement, especially the derivation and use of algebraic formulae to measure the areas , volumes and different parameters of geometric figures.

the act or process of assigning numbers to phenomena according to a rule
