Answer:
Option B.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that triangle ABC is an isosceles triangle.
From the below figure it is clear that the vertices of triangle are A(-2,-4), B(2,-1) and C(3,-4).
Distance formula:

Using this formula, we get



Now,
Perimeter of triangle ABC = AB + BC + AC


So, perimeter of triangle ABC is
units.
Therefore, the correct option is B.
