*provide details with your answer if its NECESSARY. * What is the perimeter of this triangle?

Option B is the correct answer.

Step-by-step explanation:

Finding the distance between the points A and B

A ( 3 , - 1 ) → ( x1 , y1 )

B ( 9 , - 5 )→ ( x2 , y2 )

Distance =

Finding the distance between the points B and C

B ( 9 , - 5 ) → ( x1 , y1 )

C ( 16 , - 2 )→ ( x2 , y2 )

Distance =

units

Finding the distance between the points A and C

A ( 3 , - 1 )→ ( x1 , y1 )

C ( 16 , - 2 )→ ( x2 , y2 )

Distance =

units

Now, let's find the perimeter:

Perimeter = AB + BC + AC

plug the values

Calculate

units
