Find the area of a triangle with vertices A(3, 1), B(2, -1), and C(-2, 1). Leave your answer in decimal form, rounded to the nearest hundredth.
For these problems, I'd highly recomend graphing them out. Personally, I love using desmos.

The base is 5, and the height is 2.
So the area is 5*2/2 = 5.
I hope this helped. :)))
