    \[\frac{ 1 }{ 6 }? \]

    If you cut the triangle in half, and then stack it on top of the other, and divide up the rectangle, it could be \[\frac{ 1 }{ 6 }\]

    I'm just asking for the total area of the rectangle for now. The sides of the rectangle are x and x+2. So what is the area?

    Great, now we try to find the area of the triangle. Any ideas?

    Well that happens to be the area of the total triangle which is great! So now to get the fraction we can write\[{areaOfTriangle\over TotalArea}\]

    \[{x\over(x)(x+2)}\]x's cancel.

    The fraction for the triangle is \[\frac{ 1 }{ x + 2 }\] Yes?
