The total number of unit squares in the form of a square is known as the area of a square. In other words, it is the area occupied by the square. To calculate the area of a rectangle, multiply its height by its width. To get the area of a square, find the length of one of the sides and multiply it by itself. This is equivalent to length2 or length squared.

The number of square units required to fill a square is known as its area. In general, the area is defined as the region included inside the boundaries of a flat object or 2d figure. The measurement is done in square units, with square metres being the usual unit.
