Find the area of rectangle ABCD with vertices A(-3,0)B(3,2C(4,-1)D(-2,-3)

The area of the triangle is 20. 

You can find this by plotting each of the points and drawing the triangle. You can then use the distance formula to determine each side length. The triangle will be [tex] \sqrt{40} [/tex] on one side and [tex] \sqrt{10} [/tex] on the other. When multiplied together, it will give you the above answer.
