What is the area of the triangle

Q(-2,5) R(4,5) S(-5,4)

A: 28.2

B:13.5

C:54

D:27

Explanation:

The figure attached shows the three points, Q(-2,5), R(4,5), and S(-5,4), in a coordinate plane.

The points Q and R have the same y-coordinate, then if you set them as the base of the triangle, the height from S to Q is the altitude:

Area of a triangle = base × altitude / 2

That answer does not match either answer choice. But it is the area of a triangle with the given vertices Q,R,S.

If your vertices are others, you can just follow the same procedure: find the base and the altitude and use the formula for the area used above.
