Geometery think I got it
I think I figured it out. The triangle. A= 1/2 x bxh A = 1/2 x 19 x 12 = 114cm area of for Triangle. I got the 12 because the paraelel side of 10 is 22 of the rectangle. So the triangle looks like (attached to rect.) it is 12cm.
April 21, 2013

Geometery
Yes I see what your saying. The bottom of the triangle though is apart of the side of the rectangle. But just a small portion of it. I knew my triangle something was off. A = 1/2 x 10cm???x 19cm The rectangle 10cm is paraelle to 22cm.
