Question

5. A room is 13 m long and 10 m broad. Find the cost of carpeting the floor at the rate of 6 per mस्क्वायर ​

Answer 1

Understanding the question:-

Here, a room is given with the length of 13m and breadth of 10m. We are supposed to find the cost of carpenting the floor at the rate of 6 units per meter square. In our question, length and breadth is given so its sure that floor is in the rectangular shape, not in square.

Required answer:-

Given:- length of room is 13m and breadth is 10m. Carpenting cost of per m² is Rs.6 .

Solution:-

As we know that the shape of flore is rectangular, so:-

⇒ Area of floor = length × breadth

⇒ Area of floor = 13m × 10m

⇒ Area of floor = 130m²

Now,

Rate of carpentering per m² = 6 units.

Rate of carpentering 130m² = 6 × 130

Rate of carpentering 130m² = 780 units.

Therefore, cost of carpenting the floor is 780 units of money.

Answer 2

${\large{\bold{\rm{\underline{Let's \; understand \; the \; concept}}}}}$

★ 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..!

${\large{\bold{\rm{\underline{Given \; that}}}}}$

★ Length of the room = 13 m

★ Breadth of the room = 10 m

★ Carpeting the floor at cost of 6 Rupees per metres²

${\large{\bold{\rm{\underline{To \; find}}}}}$

★ The cost of carpeting the floor at the cost of 6 Rupees per metre²

${\large{\bold{\rm{\underline{Solution}}}}}$

★ The cost of carpeting the floor at the cost of 6 Rupees per m² = Rupees 780.

${\large{\bold{\rm{\underline{Using \; concept}}}}}$

★ Area of rectangle formula.

${\large{\bold{\rm{\underline{Using \; formula}}}}}$

★ Area of rectangle = Length × Breadth

${\large{\bold{\rm{\underline{Full \; Solution}}}}}$

~ 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
