Step-by-step explanation:
Consider the following picture of the figure determined by the points (-3, -5). (-2, 7), (4, 1) and (3, -6):
Notice that this figure is similar to a parallelogram (drawn more carefully). The area of a parallelogram is given by the product of its height and base. To find the lenght of its height and base we can use the distance formula.
Then, we can conclude that the correct answer is:
Answer: The step that should not be followed to find the area is:
