Answer:
16.000Rs
Step-by-step explanation:
Let's solve this step by step.
Let's assume that the length of the room is L and the breadth is B.
Given that the length is two times the breadth, we have L = 2B.
We are also given that the perimeter of the floor is 48m, which for a rectangle is given by the formula: 2(L + B) = 48.
Substitute L = 2B into the perimeter equation, we get: 2(2B + B) = 48, which simplifies to 6B = 48.
Therefore, B = 48 / 6 = 8.
Now, we can find the length L by substituting back into L = 2B, which gives L = 2 8 = 16.
To find the area of the floor (A), we use the formula A = L B, so A = 16 8 = 128 sq. meters.
The cost of paving marbles on the floor at Rs 125 per sq. metre would be 128 125 = 16,000 Rs.
