Answer: The formula for finding the area of a triangle is A = 1/2(x1)(y2-y3)+(x2)(y3-y1)+(x3)(y1-y2).

Plugging in the given coordinates, the area of the triangle is:

A = 1/2(-3)(-1-1) + (-2)(1-(-2)) + (1)(-2-(-1))

A = 1/2(-3)(-2)+(-2)(3)+1(-3)

A = -9+6-3

A = 4

Step-by-step explanation: Step 1: Identify the formula for finding the area of a triangle: A = 1/2(x1)(y2-y3)+(x2)(y3-y1)+(x3)(y1-y2).

Step 2: Plug the given coordinates into the formula: A = 1/2(-3)(-1-1) + (-2)(1-(-2)) + (1)(-2-(-1)).

Step 3: Simplify the equation: A = 1/2(-3)(-2)+(-2)(3)+1(-3).

Step 4: Solve the equation: A = -9+6-3.

Step 5: Find the area of the triangle: A = 4.
