What is the area of the triangle in the coordinate plane?

Answer:
The area of the triangle is [tex]16\ units^{2}[/tex]
Step-by-step explanation:
we know that
The area of a triangle is equal to
[tex]A=\frac{1}{2}bh[/tex]
where
b is the base of triangle
h is the height of triangle
In this problem
Observing the graph
[tex]b=(12-8)=4\ units[/tex]
[tex]h=(10-2)=8\ units[/tex]
substitute the values
[tex]A=\frac{1}{2}(4)(8)=16\ units^{2}[/tex]
