Lengths

Length is a measure of how long something is. It is the extent of something from end to end. In the context of mathematics, length is often used to measure the size of objects or distances between two points.

Units of Length

There are several units of length commonly used in the metric system, such as:

• Meter (m)
• Centimeter (cm)
• Kilometer (km)

In the imperial system, units of length include:

• Inch
• Foot
• Yard

Measuring Length

Length can be measured using various tools such as rulers, tape measures, meter sticks, or yardsticks. When measuring, it's important to align the starting point of the object with the zero mark on the measuring tool and then read the measurement at the end of the object.
