Area of Shapes
Area is the space occupied inside by the boundary of any figure. It is the total surface covered by the perimeter of the figure. It is measured in square units. It is generally calculated by multiplying the bases of the figure with its length. For example, the area of the room is its length multiplied by its breadth.
In this article we will be learning about, some figures and their areas like the square, rectangle, circle, triangle, and others.
