Answer 1

Answer:

The cost of the carpet is Rs.15000.

Step-by-step explanation:

Given : A Rectangular room is 10 m long and 7.5 m wide.

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

Solution :

Length of the room= 10 m

Width of the room= 7.5 m

Area of the floor is

$A=l\times b$

$A=10\times 7.5$

$A=75 m^2$

Width of the carpet= 1.25 m

Now, Area of the carpet= Area of the floor

$75 m^2=L\times1.25$

$L=\frac{75}{1.25}$

$L=60$

So, Length of the carpet is 60 meter.

Rate is Rs.250/m

Cost of covering the floor is

$C=250\times 60$

$C=15000$

Therefore, The cost of the carpet is Rs.15000.
