cant see

Answer 2

Where is the square... (:

Answer 3

e

Answer 4

idont know what happen to it

Answer 5

Hahaha nice amit

Answer 6

its not allowing it to show

Answer 8

And you have to save and attach it.

Answer 9

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

Answer 10

ok

Answer 11

ok

Answer 12

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

Answer 13

yes

Answer 14

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

Answer 15

would i multiply the 12 ans 13 together?

Answer 16

if yes i got 162

Answer 17

?

Answer 18

That is the area of the square.

Answer 19

so how would i find the area of the triangle?

Answer 20

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 \(1/2(12)(5)=30\).

Answer 21

The area of the shaded portion is equal to the area of the square minus the area of the triangles. That's \(12^2-2(30)=84 m^2\)

Answer 22

how do u get 5 from 13 2 and 12 2

Answer 23

?

Answer 24

Use Pythagoras theorem. We have a side of the triangle equal to \(12\) and the hypotenuse is \(12\), so the third side is \(\sqrt{13^2-12^2}=5\).

Answer 25

I meant the hypotenuse is \(13\).

Answer 26

I'm still having a hard time understanding

Answer 27

?

Answer 28

hello anyone there

Answer 29

remyred90 you there?

Answer 30

yes

Answer 32

no

Answer 33

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

Answer 34

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

Answer 35

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

Answer 36

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

Answer 37

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

Answer 38

yea but how did he get 84

Answer 39

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

Answer 40

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.

Answer 41

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

Answer 42

okay

Answer 43

thanx

Answer 44

where did the 30 ccum from?

Answer 45

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

Answer 46

i really appreciate ur time

Answer 47

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

Answer 48

No problem. Gotta go bell is ringing.

Answer 49

ok thanx

Answer 50

i understand it now thank you so much
