Question 3 (Mandatory) (1 point) Saved
The vertices of the triangle shown below are (-2, 2), (4, -1), and (-2, -3).
What is the area of the triangle?

The answer to your question is 15 u²

Step-by-step explanation:

Data

A (-2, 2)

B (4, -1)

C (-2, -3)

Area = ?

Process

1.- To solve this problem use determinants

                  | -2   2 |

Area = 1/2  |  4  -1  |  = 1/2 [ (-2 x -1) + (4 x -3) + (-2 x 2) - (-2 x -3) - (-2 x -1)

                  | -2 - 3 |            - (4 x 2)]

                  | -2   2|

                                = 1/2 [ 2 - 12 - 4 - 6 - 2 - 8]

                                = 1/2[ -30]

                                = 1/2(30)

                                = 15 u²
