The correct Answer is:
To solve the problem of finding the area of the rectangle and the cost of its flooring, we will analyze the statements provided step by step. ### Step 1: Determine the Length of the Rectangle From Statement I, we know: - The length of the rectangle is 6 meters. ### Step 2: Calculate the Breadth of the Rectangle From Statement II, we know: - The breadth of the rectangle is two-thirds of its length. - Therefore, the breadth can be calculated as: \[ \text{Breadth} = \frac{2}{3} \times \text{Length} = \frac{2}{3} \times 6 \text{ meters} = 4 \text{ meters} \] ### Step 3: Calculate the Area of the Rectangle The area \( A \) of a rectangle is given by the formula: \[ A = \text{Length} \times \text{Breadth} \] Substituting the values we have: \[ A = 6 \text{ meters} \times 4 \text{ meters} = 24 \text{ square meters} \] ### Step 4: Convert the Area to Square Centimeters Since the cost of flooring is given per 100 cm², we need to convert the area from square meters to square centimeters: \[ 1 \text{ square meter} = 10,000 \text{ square centimeters} \] Thus, \[ 24 \text{ square meters} = 24 \times 10,000 \text{ cm}^2 = 240,000 \text{ cm}^2 \] ### Step 5: Calculate the Cost of Flooring From Statement III, we know: - The cost of flooring 100 cm² is Rs. 45. To find the cost of flooring 240,000 cm², we first find out how many 100 cm² units are in 240,000 cm²: \[ \text{Number of 100 cm}^2 = \frac{240,000 \text{ cm}^2}{100 \text{ cm}^2} = 2400 \] Now, we can calculate the total cost: \[ \text{Total Cost} = 2400 \times 45 \text{ Rs.} = 108,000 \text{ Rs.} \] ### Conclusion Thus, the area of the rectangle is 24 square meters, and the cost of flooring is Rs. 108,000.

To solve the problem of finding the area of the rectangle and the cost of its flooring, we will analyze the statements provided step by step. ### Step 1: Determine the Length of the Rectangle From Statement I, we know: - The length of the rectangle is 6 meters. ### Step 2: Calculate the Breadth of the Rectangle From Statement II, we know: ...
