Question

the Length breadth and height of a room is 15 M 10 m and 5m respectively find the cost of painting of the four walls at the rate of rupees 1000 per metre square

Answer 1

Answer:

The cost of painting is  Rs 2,50,000.

Step-by-step explanation:

Given: Length(L) = 15 meter    

           Breadth(B)=10 meter

            Height(H)=5 meter

  To find : the cost of painting of four walls

    Formula of area of 4 wall : 2H(L+B)

            = 2* 5 ( 15+10) [ According to BODMAS we need to solve the bracket first]

         =2*5(25)

          = 10*25

           =250m^2( is the area of four wall).

According to the question

1m^2= Rs 1000

So, for  250m^2= Rs 1000* 250

                         = Rs 2,50,000.
