What did you do for 170^2
Astrophysics
  • Astrophysics
\[A_{\square} =a^2~~~~~A_{\triangle} = \frac{ 1 }{ 2 }bh\]
-Welp-
  • -Welp-
Oops. I got 30-60-90 mixed up with this. I just tried using soh cah toa and got o=10 a=10 h=10^2, which doesn't make any sense. I'm not sure what to do now
Astrophysics
  • Astrophysics
I'm going to redraw it, |dw:1438255686271:dw| does this look right
-Welp-
  • -Welp-
Yes
Astrophysics
  • Astrophysics
Ok so we know that's a square and a triangle, agree?
Astrophysics
  • Astrophysics
So for the base of the triangle we can simply do \[b = 22-12 = 10\] as we know the side of the square is 12, and all the sides of the square are the same.
Astrophysics
  • Astrophysics
|dw:1438255835677:dw| so we have this now

It's a rectangle and a triangle
Astrophysics
  • Astrophysics
Well a square is a special rectangle, but if you could upload an image it would be better, but I think this is right.

"Well a square is a special rectangle" Oh http://i.imgur.com/8zzdyhK.png

  • undeadknight26
I think it's a square.
Astrophysics
  • Astrophysics
Yeah me to..looks like a square to me
undeadknight26
  • undeadknight26
Since the height is 12 and the width is 12.
Astrophysics
  • Astrophysics
Yes, it's a square, so now you can get the total area using \[A_{total} = a^2+\frac{ 1 }{ 2 }ab\] Where a = 12 b = 10
Astrophysics
  • Astrophysics
I'm going to make sure though, lets just use some trig. |dw:1438256489005:dw|
Astrophysics
  • Astrophysics
Yeah, so it's not a square...we can use the tan ratio \[\tan \theta = \frac{ opp }{ adj } \implies \tan \theta* adj = opp \implies \tan(45)*10 = opp = 10\]
Astrophysics
  • Astrophysics
So this is our new drawing |dw:1438256643590:dw| that makes much more sense as well
Astrophysics
  • Astrophysics
because a 45 - 45 - 90 triangle would have 10 base and 10 height
Astrophysics
  • Astrophysics
Boo yeah!
Astrophysics
  • Astrophysics
So we have Area of rectangle + Area of triangle = total area
Astrophysics
  • Astrophysics
\[A_{total} = lw+\frac{ 1 }{ 2 }bh \]
Astrophysics
  • Astrophysics
The original image was kind of hard to tell, maybe it's because I'm too tired :p But now you should be able to get it, just plug and chug at this stage.
