Answer:

The answer to your question is 10 units ²

Step-by-step explanation:

To solve this problem I will use the formula

                 3    3

A  =   1/2    3    -1        = 1/2  [  (3 x -1) + (3 x -5) + (-2 x 3) - (3 x -5) - (-2 x -1)

                -2   -5                     -(3 x 3)]

                 3    3        = 1/2 [ -3 - 15 - 6 + 15 - 2 - 9]

                                 = 1/2 [ -20]

                                 = 1/2|20|

                                 = 10 units²

Sorry, I don't remember how to use the formula 1/2 b x h
