You can put this solution on YOUR website! .
Use the distance formula for a pair of points in a coordinate plane.
For each of the three possible pairs of points, calculate the distance between them.
By doing this way, you will find the measures of the three sides of the triangle.
After that, simply add the three measures.
At the end, you will get your answer.
Is everything clear to you in my post/instructions ?
