Question

Plot and connect the points A(2,5), B(6,1), C(-4,1), and find the area of the triangle it forms.

Answer 1

The answer to your question is 20 units²

Explanation:

See the graph below

- Calculate the area

A = 0.5 | 2 5 | = 0.5 |(2 x 1) + (6 x 1) + (-4 x 5) - (2 x 1) - (-4 x 1) - (6 x 5)|

| 6 1 | = 0.5 | 2 + 6 - 20 - 2 + 4 - 30 |

| -4 1 | = 0.5 | 12 - 52 |

| 2 5 | = 0.5 | -40 |

= 0.5(40)

= 20 units²
