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

Answer:

The area of the triangle is $A=4\ units^{2}$

Step-by-step 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

$A=\frac{1}{2}(BC)(AB)$

$BC=8-0=8\ units$

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

substitute

$A=\frac{1}{2}(8)(1)$

$A=4\ units^{2}$
