A shop sells floor tiles at Rs 48 per square meter. A building contractor employees
machine that polishes
the tiles that damages 10% of the total number of
tiles which cannot be used
any
more. Calculate the
amount that need to be paid by contractor to tile
Shop owner, if the hall is of a square shape and
has a perimeter of 400m
a. Rs 400.000
b. Rs 600 000
c. 528000 d.365000

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

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

a is the correct
