Another way to look at this...

for the big part, |dw:1473899502360:dw|

OpenStudy (kosmetickitty):

Yeah, I got 16.5 for the area of that part.

I'm having issues finding the area of the left triangle. :/

OpenStudy (kosmetickitty):

I've currently got 3 as the area, but I don't see that being correct.

OpenStudy (mathmate):

Yes, 3 to be subtracted is correct (i.e. area=-3).

OpenStudy (mathmate):

|dw:1473899885004:dw| Area of the figure equals A+B-C where A and C are triangles, B is a rectangle.

OpenStudy (kosmetickitty):

So why wouldn't you be adding the 3 instead?
