Answer:
Measurements are used to describe quantitatively real-life situations
Explanation:
Measurement refers to the act of assigning a number (with a unit) to a characteristic of an object or an event.
For example: when we want to measure the size of an object, we can use a rule to measure its length, and we assign a number with a unit for that quantity (for example, 5 cm). In this case, we have done a measurement.
Measurements are used by scientists in order to understand the natural worlds. In fact, without measurements it would be impossible to describe phenomena of the real world quantitatively: it would be only possible to describe them qualitatively, and therefore it would not be possible for instance to derive mathematical laws that describe those phenomena.
