★ This question says that a room is 13 metres as it's length and 10 metres as it's breadth. We have to find out the cost of carpeting the floor at the cost of 6 Rupees per metre²
★ Length of the room = 13 m
★ Breadth of the room = 10 m
★ Carpeting the floor at cost of 6 Rupees per metres²
★ The cost of carpeting the floor at the cost of 6 Rupees per metre²
★ The cost of carpeting the floor at the cost of 6 Rupees per m² = Rupees 780.
★ Area of rectangle formula.
★ Area of rectangle = Length × Breadth
☆Firstly let us find the area of room..! We have to use the formula to find area of rectangle.
↝ Area of rectangle = Length × Breadth
↝ Length of floor = 13 m
↝ Breadth of floor = 10 m
↝ Area of floor = Length × Breadth
↝ Area of floor = 13 × 10
↝ Area of floor = 130 m²
☆ Now it's given that the cost of carpeting the floor at the cost of 6 Rupees per metre²
↝ Cost = 6 × 130
↝ Cost = Rupees 780
