Question 162512: Calculate the area of the triangle with the following vertices:
(-8, -2), (-1, -11), and (-1, -2)
I tried my best, and got an answer of 31.5 sq units. I just want to know if this is correct,and if not, see the steps to come to the correct answer and what it is. I thank you very much for your time!: Calculate the area of the triangle with the following vertices:

You can put this solution on YOUR website!Let's graph the points.
.
.
.
The area of a triangle is
where b is the base, h is the height of the triangle.
From the diagram,
Your answer is correct.

You can put this solution on YOUR website!First I want to see if any of the 3 lines that
connect these point is either horizontal or
vertical. that will just make the job easier
The pair of points (-1,-11) and (-1,-2) both have
the same x value, which makes the line between
them vertical.
The pair (-8,-2) and (-1,-2) have the same y value,
so the line between them is horizontal.
That means the triangle is a right triangle
The length of the 1st line is just the difference
between  and  , which is 
The length of the 2nd line is just the difference
between  and  , which is 
Using the formula 
Same as you got
