Final answer:
The measurement being referred to is the metric system, which includes the meter as a unit of length. The correct option is C.
Step-by-step explanation:
When height is measured in meters, the system of measurement being used is the metric system. Height measurement is a common example of applying the metric system, which is the standard form of measurement in science and in most countries outside of the United States. The fundamental units of the metric system include the meter for length, the kilogram for mass, and the second for time.
For instance, consider a scale model of a building with a height of 1.5 meters and a scale of 1 cm equals 0.5 meters. To find the actual height of the building, you would set up a proportion where 1 cm on the model is to 0.5 m as the model's height is to the building's actual height. By solving this proportion, you can determine that the actual building is 3 meters tall because 1.5 meters divided by the scale factor of 0.5 meters per centimeter gives you 3.
The customary system, on the other hand, is mostly used in the United States and includes units such as inches, feet, and yards for length measurement. This system does not have the simplicity of base-ten conversions seen in the metric system.
