On a piece of grid paper, plot the following points and connect them: $A(–3, –4)$, $B(2, 4)$, $C(5, –4)$

1. What is the area of triangle $ABC$

Using the etool below plot points $A$, $B$, and $C$ onto the grid where they
belong to form the triangle.

2. What is the perimeter of triangle $ABC$?

Draw a segment creating two right triangles.
Then use the Pythagorean Theorem to find
