Answer 2

C.

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
