Answer: c
Explanation: Let the side of the square shaped hall be X meter
Perimeter = 4X
4X = 400
X = 100m
Area of the hall = 100 × 100 = 10000 sq. meter.
The cost on total tiles = 10000 × 48 = Rs. 480000
But, 10% damage has occurred on tiles which will also be included in cost i.e
Total cost = 480000 + 10% of 480000 = 480000 + 48000
Total cost = Rs. 5,28,000
