    Answer:

    c. 528000

    Step-by-step explanation:

    The computation of the amount that need to be paid is shown below:

    Let us assume the side of the square shaped hall be X meter
    s

    So,

    Perimeter = 4X

    Now

    4X = 400

    X = 100m

    Now

    Area of the hall = 100 × 100 = 10000 sq. meter.

    And,

    The cost on total tiles is

    = 10,000 × 48 = Rs. 480000

    But, there is 10% damage has occurred that involved in the cost

    So,

    Total cost is

    = Rs 480,000 + 10% of 480,000

    = 480,000 + 48,000

    = Rs. 5,28,000
