What is "the side length?

The side length refers to the length of one of the sides of a geometry shape, such as a square or a rectangle. It is a measurement that describes the distance between two of the corners or vertices of the shape. In a square, all four sides have the same length, while in a rectangle, the opposite sides have the same length. The side length is an important parameter in determining the area, perimeter, and other properties of a shape. It is typically denoted by the symbol "l" or "s" in mathematical equations and formulas.
