i thought of doing it this way > \[1/2(16)(22+24)\]

- anonymous

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.

where did the 8 come from?

|dw:1336757547625:dw|
then subtract out the area that the windows cover

- amistre64

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

Ok. what does the roof hace to do with it?

- anonymous

have

- amistre64

thats not the roof, thats a gable end of the back of the house that gets painted

- anonymous

oh. lol *face to palm*

- anonymous

Keep going. :3

- anonymous

Please.

- amistre64

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

- anonymous

440

- amistre64

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

- anonymous

ok got that down.

- amistre64

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

- anonymous

sorry back

- anonymous

i got a huge desimal number

- amistre64

yep, which can be stated as 1.95

- amistre64

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
