Question

Finding the Area to ABC (plotted below). All of the examples I’ve seen only discuss points and coordinates when I’m working on an Area and Perimeter unit.

Answer 1

Step-by-step explanation:

Given the coordinates of the triangle as:

B(2, -8), C(-6, -2), and D(-7, -5)

The area is obtained using the formula:

`A=(1)/(2)\begin{bmatrix}{x_1} & y_1{} & {1} \\ {x_2} & {y_2} & {1} \\ {x_3} & {y_3} & {1}\end{bmatrix}`

Using the given parameters, we have:
