What term is used to describe the length of a path between two points?

The term that describes the length of a path between two points is "distance." When you measure how far apart two locations are, you are essentially quantifying the distance between them. This measurement can be in various units, such as miles or kilometers, depending on the context.

In practical applications, distance is a fundamental concept used in geometry and navigation. For example, if you wanted to know how far you need to travel to reach a friend's house, you would measure the distance from your location to theirs. The other terms, while related to measurements of space, do not specifically refer to the length of a path between two points. Width refers to the measurement of how wide an object is, height refers to the measurement from base to top, and diameter is a specific measurement across a circle, passing through its center.
