Answer:
The correct option is C.
The perimeter is 37.5
Explanation:
The perimeter is the sum of the lengths of the sides of the triangle.
The sides have the following coordinates:
(-8, 7), (2, -4), and (6, 3)
We find the length from
(-8, 7) to (2, -4)
(2, -4) to (6, 3)
(6, 3) to (-8, 7)
The lengths are:
[tex]\sqrt[]{221},\sqrt[]{65},\sqrt[]{212}[/tex]
The perimeter, therfore, is:
[tex]\sqrt[]{221}+\sqrt[]{65}+\sqrt[]{212}=37.5[/tex]
