Area of Rectangle

Area of Rectangle - illustration

To calculate the area of a rectangle, we need to know the length of its two sides. The rectangle is 2D shape, which has two pairs of parallel sides. The first pair is longer or shorter than the second pair. They are never the same length. If the first pair is the same length like the second pair, it is a square. Every inside angle is perpendicular. The area of a rectangle means a size of a cover area by the rectangle. For example, the area of a rectangle garden. The elementary unit of the area is one square metre, it means the second power of one metre (1 m2).
