According to your question
Length is equal to 50 m
Breadth is equal to 30 m
Height is equal to 2.5 m
So, LSA is equal to 2*h(l+b)
is equal to 2*2.5(50+30)
is equal to 5*80
is equal to 400 m sq
Now, floor area is l* b
is equal to 50*30
is equal to 1500 m sq
Total area to be painted is equal to 1500+400 is equal to 1900 m sq.
Since 1msq cost is $27
therefore 1900 m sq is 27*1900 is equal to $51300
Length is equal to 50 m
Breadth is equal to 30 m
Height is equal to 2.5 m
