Answer 2

Correct Question:

Find the cost of carpeting a room 12 m length and 9 m breath at the rate of Rs. 5 per square meter.

Answer:

• Cost of carpeting a room is Rs. 540.

Step-by-step explanation:

Given:

• Length of room = 12 m
• Breadth of room = 9 m

To Find:

• Cost of carpeting a room.

Now, first we will calculate area of room,

⇒ Area of room = Length × Breadth

⇒ Area of room = 12 m × 9 m

⇒ Area of room = 108 m²

Hence, Area of a room = 108 m².

Now, it is given that the rate of carpeting room is Rs. 5 per m².

Hence, Rate of carpeting of 108 m² room is,

⇒ 5 × 108

⇒ Rs. 540.

Hence, cost of carpeting a room is Rs. 540.
