## ZyairaBoyd 3 years ago I need to make sure im about to do this right can someone coach me?

1. ZyairaBoyd

2. ZyairaBoyd

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

3. dpaInc

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.

4. ZyairaBoyd

Oh......

5. ZyairaBoyd

mind showing and example?

6. dpaInc

example of what?

7. ZyairaBoyd

im more of a visual learner

8. ZyairaBoyd

and example of what ur talking abt liker maybe draw it out

9. amistre64

dont you already have a drawn out example in front of you?

10. ZyairaBoyd

no i mean liker his example....of what he told me to do

11. amistre64

he explained the example that you gave him .....

12. ZyairaBoyd

Never mind -.-

13. amistre64

|dw:1336757446056:dw| determine the area of the rectangle and the triangle; then add the results

14. dpaInc

sorry, i need to leave. but it looks like you're with the master now... :)

15. ZyairaBoyd

where did the 8 come from?

16. amistre64

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

17. amistre64

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

18. ZyairaBoyd

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

19. ZyairaBoyd

have

20. amistre64

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

21. ZyairaBoyd

oh. lol *face to palm*

22. ZyairaBoyd

Keep going. :3

23. ZyairaBoyd

24. 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

25. ZyairaBoyd

440

26. 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

27. ZyairaBoyd

ok got that down.

28. 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

29. ZyairaBoyd

sorry back

30. ZyairaBoyd

i got a huge desimal number

31. amistre64

yep, which can be stated as 1.95

32. 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

33. ZyairaBoyd

tysm

34. amistre64

youre welcome

35. ZyairaBoyd

it says it was wrong ;\

36. ZyairaBoyd

:\

37. amistre64

what did you enter as an answer?

38. ZyairaBoyd

1.95......

39. amistre64

try 2

40. ZyairaBoyd

it says yes

41. ZyairaBoyd

2 was correctt

42. ZyairaBoyd

43. amistre64

yep, thats how we solved it :)

44. ZyairaBoyd

Yay.
