Question

A triangle has vertices at (-2, 1), (1, 1), and (1, -3). Find its area and round to the nearestwhole number if necessarv. Do not include units in your answer.

Answer 1

Given:

A triangle has vertices at (-2, 1), (1, 1), and (1, -3).

We will draw the vertices to form the triangle.

The graph of the triangle will be as shown in the following picture:

As shown, it will be a right-angle triangle

The base of the triangle = 3 units

The height of the triangle = 4 units

The area of the triangle will be as follows:

`Area=(1)/(2)*base*height=(1)/(2)*3*4=6`

So, the answer will be:

Area of the triangle = 6
