Readers ask: What Is Area In Mathematics?

How do I figure out area?

To work out the area of a square or rectangle, multiply its height by its width. If the height and width are in cm, the area is shown in cm². If the height and width are in m, the area is shown in m². A square with sides of 5 m has an area of 25 m², because 5 × 5 = 25.
