Answer 1

Answer:

Step-by-step explanation:

Area =Length*width;

Area of wall=12*10=120sq.m;

Area of Window=2*2.5=5sq.m;

We are considering that the window is not to be painted;

So total area to be painted=120-5=115sq.m(except area of Window)

Coat of painting=5.5 per sq.m.;

So cost of painting to 115 sq.m is= 115*5.5=632.5rupees
