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.
