## IMO Class 2 Chapter 5: Length Detailed Notes

When we see heights like hills, towers, buildings, long trees, bridges, tracks, and so on, we often think about how tall they are. In such cases, we usually take the height of the objects into account. This height is also known as the length of a particular thing. For instance, the length of the bridge or track. In this article, you will learn the definition of length, as well as units, conversion rules, and additional information, including detailed examples.

### Definition of length

The measurement or extent of something from end to end is defined as length. In other words, it is the larger of the two or the highest of three geometrical shapes or objects’ dimensions. A rectangle, for example, has length and breadth dimensions. In the International System of Quantities, length is also a quantity with the dimension distance.

### Unit of length

As defined in the preceding section, length is a unit of measurement. The question now is how to express length in a way that everyone can understand the original aspect. The meter is the base unit for length in the International System of Units (SI) system, and it is abbreviated as m. This is possible when the length is expressed in appropriate units, such as 2 meters or 200 cm for a table, 15 meters for a string, and so on. Thus, the units of measurement will aid in comprehending the numerical parameters.

### Converting Lengths

The metric system expresses length or distance in kilometers (km), meters (m), decimeters (dm), centimeters (cm), and millimeters (mm) (mm). Units can be converted from km to m, m to cm, cm to mm, and so on.

### How Do You Determine Length?

The length of any object can be determined using various methods such as a scale (i.e., ruler), measuring tape, and so on. These instruments are typically used to determine the length of various objects. A ruler is used to measure small objects because its maximum length is 30 cm. If the object’s length is greater, a measuring tape will be used to make the measurement quick and easy.

### How to Prepare for a Math Olympiad

Planning is especially important when an understudy is participating in a serious test, such as the International Math Olympiad.
