What is Area and Perimeter?
Mensuration is a part of geometry. It helps in solving shape-related problems and comes in very handy in everyday lives. The two most basic elements of mensuration are area and perimeter.
Perimeter is the measure of the total length of the boundary of a 2D shape. The Sum of all sides is how you can calculate the perimeter of a shape. When talking about the circle, the measure of the total length of the boundary is what we term as the circumference.
The area is the measure of the space enclosed within the boundary of a 2D shape. There are different formulae to calculate the area of different shapes.
Rectangle: L × B
Triangle: 1/2 × base × height
