A triangular region is enclosed by the lines with equations 1) y = 1/2 x + 3, 2) y = -2x + 6 and 3) y = 2. What is the area of the triangular region? Express your answer as a decimal to the nearest hundredth.

$$P_{1,2}\\ \frac{1}{2}x+3=-2x+6\\ x=\frac{6}{5}\\ y=3.6$$

$$P_{1,3}\\ 0.5x+3=2\\ x=-2\\ y=2$$

$$P_{2,3}\\ -2x+6=2\\ x=2\\ y=2$$

$$A=(2-(-2))\cdot (3.6-2)/2$$

$$A=3.2$$
