Subtracting the labour cost of Rs. 3,500 from the total cost of Rs. 14,500 leaves a material cost of Rs. 11,000. Dividing this material cost by the rate of Rs. 250 per square meter gives the area of the hall as 44 square meters. This requires the total cost from statement three, the labour cost from statement two, and the per-square-meter rate from statement one, meaning all three statements are necessary.
