Math Problem Statement
Solution
Let's break down the task from the image:
We are asked to graph the triangle formed by points , , and , and calculate its perimeter.
The figure shows that the correct graph is option . To find the perimeter, we need to calculate the distances between the points , , and using the distance formula.
Distance Formula:
For two points and , the distance between them is:
1. Distance :
Points: ,
2. Distance :
Points: ,
3. Distance :
Points: ,
Perimeter:
Now, we sum the distances:
The perimeter of triangle is approximately 19.4 units.
