Answer 1

Answer:

Step-by-step explanation:

Given: Dimensions of hall: 24 m long and 18 m broad

To find:  the cost of carpeting a hall?

Solution:

Now we have given the dimensions of hall as:

                 24 m long and 18 m broad

So area of hall is: 24 x 18 = 432 m^2

Now we have given the width of carpet as 0.8 m

So, length of carpet will be = area / width

                 432 / 0.8 = 540 m

So now the cost of carpet is at the rate of rs 8 per sq. m.

So, the total cost will be:

                 540 x 8 = Rs 4320

Answer:

           So the cost is Rs 4320.
