 Hi and welcome to the session. Today we will learn about area of closed figures. So first of all let's see what is the area, the amount of surface enclosed by a closed figure is called its area. So here in this rectangle this much portion is the area of this rectangle and in this circle this portion is the area of this circle. Now let's learn how to find out the area of a figure using a square paper. Well we have a square paper and we need to find out the area of this triangle using this square paper and we can see these squares like this one. So if we are given one square then the area of this whole square will be one square units will be equal to one square units for this square which is more than half. The area will be again one square. So here let us write more than half will be equal to one square units for the square which is exactly half the area of square units. So here we have for exactly half will be equal to half that is 1 by 2 square units and the squares which are less than half will be ignored that is their area will be taken as 0 square units will be equal to 0 square units. So using these conventions we will find out the desired area let's go back to our figure that is the triangle. Here we have more than half is square half is squares so here the area of the triangle will be 6 into 1 square units as the area of whole square that is full square is 1 square unit so area of 6 squares will be 6 square units now the area of more than half square is 1 square unit and we have 6 more than half squares so again it will be 6 square units 0 half squares so it will be 0 square equal to 12 square units. Find out area of a rectangle is cd with its length denoted as l and breadth denoted as length into breadth. The angle is 4 centimeters and breadth of the rectangle is 3 centimeters to be equal to a unit that is a into a the area of a square with each side equal to 4 centimeters then its area will be equal to 4 centimeters into 4 centimeters 16 centimeters down the area of a rectangle and a square. Hope you must have understood the concepts I stay.
