Question

The length of the room is 3 times of its breadth. If the breadth of the room is 20ft. What will be the cost of carpeting the floor of the room at the rate of Rs. 75 per square ft.

A) Rs. 15,000

B) Rs. 45,000

C) Rs. 60,000

D) Rs. 90,000

E) Rs. 120,000

Answer 1

The cost of carpeting the floor of the room at the given rate is Rs. 90,000.

Step-by-step explanation:

To find the length of the room, we can multiply the breadth by 3: Length = 3 * 20 = 60ft.

The area of the room is calculated by multiplying the length and breadth: Area = 60ft * 20ft = 1200ft².

To find the cost of carpeting the floor, we can multiply the area by the rate per square foot:

Cost = 1200ft² * Rs. 75/ft² = Rs. 90,000. Therefore, the answer is D) Rs. 90,000.
