길이 refers to the measurement of how long an object is from one end to the other. It is a fundamental concept in geometry and is often measured in units such as meters, centimeters, or inches. Understanding 길이 is essential in various fields, including construction, engineering, and everyday activities like measuring furniture or fabric. In mathematics, 길이 can be calculated using different formulas depending on the shape of the object. For example, the 길이 of a rectangle is found by adding the lengths of all its sides. Accurate measurements of 길이 help ensure precision in design and construction projects.
