area of the door=2*4=8 m2
area of the window=3*2=6*2=12 m2
area of the wall=15*10=150m2
area for white wash=150-(12+8)=130 m2
total cost of white wash=130*$12=$1560

Answer:
$1,560
Step-by-step explanation:
The area of wall=l×b
=15×10
=150m^2
The area of two windows=2×(l×b)
=2×(3×2)m^2
=12m^2
The area of door=l×b
=4×2
=8m^2
The area that will not be white wash=8+12
=20m^2
The area that will be white wash=150-20
=130^2
The cost of white washed=130×12
=$1,560
