Answer 1

White washing means we need to take out csa of cuboid that is room ..... 2(l+b)h

By applying this you will get 91m^2

Now we need ro subtract 2(area of window) and multiply it by the rate which is 15

By this you will get the answer that is 1344 es

Answer 2

the area of the wall = 2 ( l+b)h - (area of two windows + area of two doors )

= 2 ( 7.4 + 5.6 ) 3.5 - ( 1.5 (1) + 1.5(2) )

=  91 - ( 4.5 )

= 86.5 $cm^{2}$

 cost = 15 x 86.5 

        = 1297.5 rupees
