## Bossvideogamer21 one year ago can someone explain to me what i did wrong?

1. Bossvideogamer21

Find the area of the figure. Assume all figures are made up of parallelograms and triangles. A. 48 m2 B. 60 m2 C. 108 m2 D. 135 m2 i

2. Loser66

What did you do?

3. Bossvideogamer21

i found the area of each parellogram( i put it into thrre) then i added the areas up and got 162, did i get it wrong or is there one more step i forgot?

5. Loser66

Fill up , please. I am guiding you.

6. Bossvideogamer21

|dw:1444600745723:dw| this is what i drew on my paper then i found out the area`s of each one

7. Bossvideogamer21

so i got 72,36,54 then added them up and got 162

8. Loser66

|dw:1444600856689:dw|

9. Bossvideogamer21

oh so, the area is 108

10. Loser66

yup

11. Loser66

|dw:1444600958271:dw|

12. Bossvideogamer21

oh no. its the side that is perpendicular, 6 x 12 , 3 x 12 , and 9 x 6. thats why theres those little squares.

13. Loser66

14. Loser66

|dw:1444601170910:dw|

15. Loser66

our diagram is |dw:1444601223224:dw|

16. Bossvideogamer21

wait im remembering what to do........

17. Bossvideogamer21

dont i subtract the what i got from the total area of the shape?

18. Loser66

if you want to subtract, you must find the biggest one, then subtract the part NOT in the diagram

19. Bossvideogamer21

so we need to figure out the total area but thats where i dont get how to find the total are

20. Loser66

|dw:1444601396943:dw|

21. Loser66

|dw:1444601430859:dw|

22. Bossvideogamer21

but then the answer would be 27, which is not one of the choices

23. Bossvideogamer21

watch this u will understand what im talking about : http://k12.http.internapcdn.net/k12_vitalstream_com/CURRICULUM/538329/CURRENT_RELEASE/MS_M6_S1_03_07_WHB_area_complex_figure.htm

24. Loser66

9*21 = 189 6*9 = 54 ----------- 189 -54 = 135 same as the previous method.

25. Loser66

I trust myself. :)

26. Bossvideogamer21

i trust u too. what is a tip of advice for these type of problems @Loser66 ?

27. Loser66

find the biggest one , find the lost parts subtract them.

28. Bossvideogamer21

thank u soo much.

29. Bossvideogamer21

30. Bossvideogamer21

there`s no lost parts

31. Bossvideogamer21

in this one so how do i do this one

32. Bossvideogamer21
