Question

What is the length? Name four early units of measurement of length.

Answer 1

Hint: We compare two objects by the use of measurements. In the measurement, we measure the size of the object. We measure length, if the object is linear. If the object has two dimensions, then we measure length and width and in the case of a three-dimensional object, we measure length, width, and height.

Complete step-by-step solution:
Length: The length of an object provides information about how long the object is. Simply, we measure the distance from one point to another point to get the length of the object. In SI and other systems of units, the length is taken as the base unit and multiple units are derived by using this unit as a base unit.

The measure of length is represented by the number with a unit of length and we have various units for the length of our measurement system. If one can measure the object in meters, then others can also measure the same object in centimeters, and these units of length have a relationship that makes them interchangeable. The four units of the measurement of the length are given as follows,
- Metre
- Centimetre
- Millimetre
- Kilometre

We use metre as the base unit of length in our SI system and centimetre as the base unit of length in CGS system.

Note:
The length provides us the value of the measurement that tells that linear dimension or the distance between the two endpoints of the object. By using the length and other dimensions, we can calculate the area and the volume of an object.
