What is the area of the shaded portion within the square?
anonymous
  • anonymous
its not allowing it to show
anonymous
  • anonymous
And you have to save and attach it.

You have to save and attach it... ^_^

Do you know how to find the area of a triangle?
anonymous
  • anonymous
yes
anonymous
  • anonymous
Good. Can you find for me the area of either one of the two triangles inside the square?
anonymous
  • anonymous
would i multiply the 12 ans 13 together?
anonymous
  • anonymous
if yes i got 162
anonymous
  • anonymous
?
anonymous
  • anonymous
That is the area of the square.
anonymous
  • anonymous
so how would i find the area of the triangle?
anonymous
  • anonymous
Well, you should first use Pythagoras theorem to find the other side of the triangle, which would be \(\sqrt{13^2-12^2}=5\). Now the area of each triangle is \(1/2(12)(5)=30\).
anonymous
  • anonymous
The area of the shaded portion is equal to the area of the square minus the area of the triangles. That's \(12^2-2(30)=84 m^2\)
anonymous
  • anonymous
how do u get 5 from 13 2 and 12 2
anonymous
  • anonymous
?
anonymous
  • anonymous
Use Pythagoras theorem. We have a side of the triangle equal to \(12\) and the hypotenuse is \(12\), so the third side is \(\sqrt{13^2-12^2}=5\).
anonymous
  • anonymous
I meant the hypotenuse is \(13\).
anonymous
  • anonymous
I'm still having a hard time understanding
anonymous

?

hello anyone there
anonymous
  • anonymous
remyred90 you there?
anonymous
  • anonymous
yes
anonymous

did you get an answer?
anonymous
  • anonymous
no
anonymous
  • anonymous
okay, give me the full question again. I will try to help.
anonymous
  • anonymous
i understand the last stuff he wrote but i didnt get the last part
anonymous
  • anonymous
I think that you don't have enough information. Wouldn't you need to have the lenght of the shaded area first?
anonymous
  • anonymous
look at what the person that was helping me was writing and c if u understand plzz
anonymous
  • anonymous
I see that the answer is 84. It makes sense.
anonymous
  • anonymous
yea but how did he get 84
anonymous
  • anonymous
i got the part where he got 5 but afta that idk
anonymous
  • anonymous
2 triangles times 30 (the area of each)=60, and 12 times 12 is 144. Subtract the 60 from the 144 and you get 84.
anonymous
  • anonymous
ok let me try this plz give me time to understand before u leave me lol
anonymous
  • anonymous
okay
anonymous
  • anonymous
thanx
anonymous
  • anonymous
where did the 30 ccum from?
anonymous
  • anonymous
well, you use the pythagorem therom. a squared plus b squared equalls c squared.
anonymous
  • anonymous
i really appreciate ur time
anonymous
  • anonymous
and the area of a triangle = 1/2 times the base times the height of the triangle.
anonymous
  • anonymous
No problem. Gotta go bell is ringing.
anonymous
  • anonymous
ok thanx
anonymous
  • anonymous
i understand it now thank you so much
