What is the area of the shaded portion within the square?

- anonymous

its not allowing it to show

- anonymous

And you have to save and attach it.

Do you know how to find the area of a triangle?

- anonymous

yes

- anonymous

Good. Can you find for me the area of either one of the two triangles inside the square?

- anonymous

would i multiply the 12 ans 13 together?

- anonymous

if yes i got 162

- anonymous

?

- anonymous

That is the area of the square.

- anonymous

so how would i find the area of the triangle?

- 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

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

how do u get 5 from 13 2 and 12 2

- 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

I meant the hypotenuse is \(13\).

- anonymous

I'm still having a hard time understanding

hello anyone there

- anonymous

remyred90 you there?

- anonymous

yes

- anonymous

did you get an answer?

- anonymous

no

- anonymous

okay, give me the full question again. I will try to help.

- anonymous

i understand the last stuff he wrote but i didnt get the last part

I think that you don't have enough information. Wouldn't you need to have the lenght of the shaded area first?

- anonymous

look at what the person that was helping me was writing and c if u understand plzz

- anonymous

I see that the answer is 84. It makes sense.

- anonymous

yea but how did he get 84

- anonymous

i got the part where he got 5 but afta that idk

- 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

ok let me try this plz give me time to understand before u leave me lol

- anonymous

okay

- anonymous

thanx

- anonymous

where did the 30 ccum from?

- anonymous

well, you use the pythagorem therom. a squared plus b squared equalls c squared.

- anonymous

i really appreciate ur time

- anonymous

and the area of a triangle = 1/2 times the base times the height of the triangle.

- anonymous

No problem. Gotta go bell is ringing.

- anonymous

ok thanx

- anonymous

i understand it now thank you so much
