Answer:
5 sqrt(10) square units
Step-by-step explanation:
The coordinates of the points A, B, and C are (-6,-2), (2,-8), and (-4,-6), respectively.
To find the area of a triangle, we can use the following formula:
Area of a triangle = 1/2 * base * height
We can use the distance formula to find the length of the base, which is AB:
Substituting the coordinates of A and B, we get:
Now, we need to find the height of the triangle. The height of a triangle is the perpendicular distance from a vertex to the opposite base. In this case, we can draw a perpendicular line from C to AB:
[Image of triangle ABC with line segment CD drawn perpendicular to AB]
The length of CD is the height of the triangle. We can use the distance formula to find the length of CD:
Now, we can find the area of the triangle:
Area of triangle ABC = 1/2 * base * height = 1/2 * 10 * sqrt(10) = 5 * sqrt(10)
Therefore, the area of triangle ABC is 5 square roots of 10 square units.
