First we are going to draw the triangle using the given coordinates.
Next, we are going to use the distance formula to find the sides of our triangle.
Distance formula:
Distance from point A to point B:
![d_{AB}= \sqrt{[6-(-9)]^2+(10-5)^2}](https://tex.z-dn.net/?f=d_%7BAB%7D%3D%20%5Csqrt%7B%5B6-%28-9%29%5D%5E2%2B%2810-5%29%5E2%7D%20)
Distance from point A to point C:
![d_{AC}= \sqrt{[2-(-9)]^2+(-10-5)^2}](https://tex.z-dn.net/?f=d_%7BAC%7D%3D%20%5Csqrt%7B%5B2-%28-9%29%5D%5E2%2B%28-10-5%29%5E2%7D)
Distance from point B from point C
Now, we are going to find the semi-perimeter of our triangle using the semi-perimeter formula:
Finally, to find the area of our triangle, we are going to use Heron's formula:
We can conclude that the perimeter of our triangle is 140.13 square units.
