Answer:
the area of the triangle is 4 square units.
Step-by-step explanation:
Plotting the points, we can see that the triangle is isosceles lying in the 4th quadrant of graph.
we can break the triangle in 2 similar right angled triangles,
each with base 2 and height 2 units.
area of triangle is given by the formula,
A= [tex](\frac{1}{2})(base)(height)[/tex]
thus, A= [tex](\frac{1}{2})(2)(2)[/tex]
A=2 square units.
there are 2 such triangles,
thus total area is 4 square units.
