b.Rs 600 000
c. 528000 d.365000​

Answer 1

c. 528000

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
