Answer 2

Answer:

5000 rupees

Step-by-step explanation:-

There are 6 steps in the answer:-

1/6. Let's find the area of the room to compare the cost of tiling it with granite and marble.

2/6. Area of the room

Room length = 5 m

Room breadth = 2.5 m

Room area = l × b

                   = 5 m × 2.5 m = 12.5 sq. m

3/6. Let's multiply the room area with the cost of granite per square metre to find the cost to tile the room with granite.

Granite cost

= 12.5 sq. m × 600 rupees/sq. m

= 7500 rupees.

4/6. Now, let's multiply the room area with the cost of marble per square metre to find the cost to tile the room with marble.

Marble cost

= 12.5 sq. m × 1000 rupees/sq. m

= 12500 rupees.

5/6. Marle cost - Granite cost = (12500 - 7500) rupees.

6/6. The additional cost of using marble to tile the floor instead of granite is 5000 rupees.
