Sue has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.

2. anonymous

What does the polygon look like?

3. anonymous

|dw:1434040381668:dw| This c:

4. anonymous

If you could explain how we do it and not give answer that will be amazing? thanks (:

5. anonymous

Yop thats what i do... Do u have any ideas?

6. anonymous

I'm not sure where to start? and how to do it. ):

7. anonymous

So you have no ideas at all at this point?

8. anonymous

No im sorry... im just confused.

9. anonymous

ok, ok... and what math is this?

10. anonymous

Yes..

11. anonymous

I mean like is this Algebra or geometry or what?

12. anonymous

Like which class

13. anonymous

geometry i think

14. anonymous

15. anonymous

ohhhhhhhhh I see

16. anonymous

yeah

17. anonymous

And this picture is the exact picture?

18. anonymous

yes but i made it on here where it says draw

19. anonymous

One of your sides says 25ft, but another side that is shorter says 35ft. Im just wondering ifthat was a typo?

20. anonymous

No its exact

21. mathstudent55

Usually with a compound polygon like that, you try to divide it into two or more smaller simpler polygons whose areas you know how to calculate. For example, divide it into rectangles, squares, trapezoids, triangles.

22. anonymous

I know that part but i just dont know how i should do it i dont wanna do it wrong. @mathstudent55

23. anonymous

Also one of your sides is cut off so i cant see the measure

24. anonymous

Its all the way to the right

25. anonymous

|dw:1434041096387:dw|

26. anonymous

its is 43ft

27. anonymous

|dw:1434041125332:dw|

28. anonymous

the middle rectangle would be 8*35

29. anonymous

uh huh

30. anonymous

|dw:1434041171151:dw|

31. anonymous

what is 43-35?

32. anonymous

8

33. anonymous

good job!

34. anonymous

thanks

35. anonymous

|dw:1434041240323:dw|

36. anonymous

what is 8*8/2?

37. anonymous

32?

38. anonymous

yes good job!

39. anonymous

(:

40. anonymous

|dw:1434041311588:dw|

41. anonymous

you understand why we did that, right?

42. anonymous

yes to find that area

43. anonymous

yes becaues the area of a triangle is 1/2*Base*Hieght

44. anonymous

yep

45. anonymous

Do you know what 35*8 is?

46. anonymous

280 i think

47. anonymous

yes

48. anonymous

and you know what 33-8 is?

49. anonymous

25

50. anonymous

|dw:1434041496831:dw|

51. anonymous

Do you know how to do the rest?

52. anonymous

add 280 + 25+ 32 ?

53. anonymous

|dw:1434041595334:dw| We still have to find that triangle

54. anonymous

25?

55. anonymous

No, its side is 25. We have to find its other side and multiply the two and divide by two

56. anonymous

oh

57. anonymous

um

58. anonymous

How dpo we find it?

59. anonymous

-do

60. anonymous

|dw:1434041926192:dw| You're sure that side "X" is actually 25?

61. anonymous

yes

62. anonymous

hmmmmmm

63. anonymous

|dw:1434042045583:dw| If the other side is 43, then how can that one be 25?

64. anonymous

i didnt create the question its on my worksheet

65. anonymous

But are you sure that you copied the question right??

66. anonymous

yes i have it with me

67. anonymous

lets see if @mathstudent55 can help us

68. anonymous

alright

69. anonymous

Bump the question up to the top real quick

70. anonymous

thank you though for attempting to help me when the question was a bit confusing.

71. anonymous

ok

72. anonymous

73. anonymous

ok

74. anonymous

there

75. anonymous

one sec im going to be right back

76. anonymous

ok

77. anonymous

78. anonymous

and you're absolutely %100 sure that the problem is copied exactly??

79. anonymous

yes i promise

80. anonymous

is the problem multiple choice?

81. anonymous

no written

82. anonymous

well... i dunno... If i were you i would assume the other side to be 25. Then do 1/2*25*25. and then add 280 and 32 to it

83. anonymous

i cant assume i need to know because i need to get it correct

84. anonymous

then call the other side "X" and do 1/2*25*X. and then add on 280 and 32

85. anonymous

i just need help understanding and doing it...

86. anonymous

im just going to close question and start over

87. anonymous

hold on, brb

88. anonymous

ok

89. anonymous

90. Here_to_Help15

Heyo

91. anonymous

hi were you doing the problem?

92. Here_to_Help15

I have already finished just viewing :)

93. anonymous

so you understand it?

94. Here_to_Help15

Yes

95. Here_to_Help15

I just want to see what @Da_Homie can do

96. anonymous

97. anonymous

I need to know the answer but i need know how to do it

98. Here_to_Help15

Ok @mathstudent55 will help with that i got to help someone.

99. anonymous

ok.. thanks i guess @Here_to_Help15

102. mathstudent55

area of triangle: 1/2 * b * h = 1/2 * 25 * 27 = 337.5 ft^2 area of trapezoid: 1/2 * (a + b)h = 1/2 * (43 + 35)(8) = 312 ft^2 total area: 337.5 ft^2 + 312 ft^2 = 649.5 ft^2
