so i'm unsure with that picture... obviously they gave dimensions of the windows so you could subtract the amount of paint needed to cover their area. but what about that red part? is that to be painted also?
that formula you put is ok if you're gonna paint that red part.

notice that the height in the middle of your picture is 24; and that the sides are 16
24 - 16 = 8 ....

since we split the house into sections, a rectangle and a triangle; lets find the area of each on
what is 16*22? for the rectangle part?
what is 8*22/2 for the triangle?
add em up

good, and since we do not want to paint the windows (i assume) lets subtract the area of the 2 windows:
2*5*3 = area of 2 windows

this gives us the total area we needed to cover, and it tells us that 1 quart covers 210 of it
divide the area we have by 210 to find out how many times (or quarts) we would need

so, you either need to be accurate in your answer to a certian decimal place; or, approximate it up to 2; but that depends on what your program is looking for
