Answer:Rs. 1,799
Step-by-step explanation:
area of the room = 2( l*b+b*h+l*h)
=2[(12.5*9)+(9*7)+(12.5*7)]
= 2(112.5+63+87.5)
=2*263
=526 sq.m
Area of doors and windows
=(2*2.5*1.5)+(4*1*1.5)
=6+6
=12 sq.m
Area needed to be painted
=526-12
=541 sq.m
Cost of painting the wall
=Rs. 3.50*514
=Rs. 1,799.
Thank you
