P. Of room =2multiple By(L+ B )
2 multiple by (10+7.5)
2 multiple by(17. 5)
35

Cost of per metre =₹250
Cost of 1.25 metre =1.25 multiple by 250= 312. 5

Answer 2

Answer:

The cost of covering the floor is Rs. 15000.

Step-by-step explanation:

Given : A rectangle room is, 10m long and 7.5"m wide.

To find : The cost of covering the floor with carpet 1.25 m wide at Rs 250 per meter.

Solution :

Length of the room= 10 m

Width of the room=7.5 m

Area of the floor is

$A=10\times 7.5= 75m^2$

Width of the carpet=1.25 m

Now, Area of the carpet = Area of the floor

So, length of carpet is

$l=\frac{75}{1.25}=60m$

Cost of per meter = ₹250

Hence, cost of covering the floor is

$C=250\times 60=Rs.15000$

Therefore, The cost of covering the floor is Rs. 15000.
