Answer:
C.
Step-by-step explanation:
To find the perimeter, we'll use the distance formula
Distance Formula = √(x₂-x₁)²+(y₂-y₁)²
Finding Distance of AB
|AB| = √(-2+5)²+(3+1)²
|AB| = √25
|AB| = 5
Now For BC
|BC| = √(6+2)²+(-3-3)²
|BC| = √(8)²+(-6)²
|BC| = √100
|BC| = 10
FOR CA:
|CA| = √(-5-6)²+(-3+1)²
|CA| = √125
Perimeter of Triangle = 10 + 5 + √125
= 15 + √125
