Question

What is the area of a triangle with vertices at (0, −2) , ​ (0, −3) ​ , and ​ (8, -3) ​ ?Enter your answer in the box.___ units²

Answer 1

The area of the triangle is
`A=4\ units^(2)`

Explanation:

Let

A(0, −2),B​ (0, −3) and ​ C(8, -3)

Plot the vertices

see the attached figure

Triangle ABC is a righ triangle

The area of the triangle ABC is equal to

`A=(1)/(2)(BC)(AB)`

`BC=8-0=8\ units`

`AB=-2-(-3)=1\ units`

substitute

`A=(1)/(2)(8)(1)`

`A=4\ units^(2)`
