Question

Solve each problem.21) Triangle ABC is a right triangle on the coordinate system and its vertices are (-2,5), (-2, 1), and (1,1). What is the area of triangle ABC? __________

Answer 1

Okay, here we have this:

Considering the provided information, we obtain the following graph:

Here, we can see that base is 3 units, and height is 4 units, so replacing in the Area Formula, we obtain that:

Area of the triangle=1/2(b)(h)

Area of the triangle=1/2(3)(4)

Area of the triangle ABC=6 units²
