 In this session we discuss the following question which says the floor of a rectangular hall is 20 meters long and 18 meter wide. How many carpets each of length 2 meters and breadth 3 meters will be required to cover the floor of the hall. Before moving on to the solution let's recall the formula for the area of a rectangle. This is equal to L into B square units where we have L is the length of the rectangle and B is the breadth of the rectangle. This is the key idea to be used for this question. Now let's move on to the solution. Now we are given that the length of the rectangular hall is equal to 20 meters then the breadth of the rectangular hall is equal to 18 meters. So now the area of the rectangular hall is equal to 20 into 18 meters square that is equal to 360 meters square is the area of the rectangular hall. Now the length of a carpet is given as 2 meters and the breadth of the carpet is given as 3 meters so the area of a carpet is equal to length into breadth meters square that is equal to 6 meters square is the area of a carpet. Now the number of carpets required to cover the hall would be given by the area of the rectangular hall divided by the area of a carpet. So we get this is equal to now the area of the hall is 360 meters square upon the area of a carpet which is 6 meters square. Now 6, 60 times is 360 so this is equal to 60 that is the number of carpets required to cover the hall is 60 so 60 is our final answer. This completes the session hope you have understood the solution for this question.
