How is the area of a rectangle calculated?

The area of a rectangle is calculated by multiplying its length by its width. This mathematical principle is foundational in geometry, representing the total space enclosed within the rectangle's four sides.

To break it down further, the length is one side of the rectangle, and the width is the other side that is perpendicular to the length. By multiplying these two dimensions, you obtain the total number of square units that can fit within the rectangle. This calculation is crucial not only in mathematics but also in various real-life applications, such as determining the amount of paint needed to cover a wall or the flooring required for a room.

Understanding this concept allows you to apply it to more complex geometrical problems and real-world scenarios where area measurement is essential.
