Answer:

36 units ⇒ Answer 1 is correct

Step-by-step explanation:

To find the perimeter of a triangle you have to simply add the 3 sides together.

They have given the lengths of three sides as follows.

9 , 12 , 15 units

Let us solve now.

Perimeter = 9 + 12 + 15

                 = 21 + 15

                 = 36 units

Hope this helps you :-)

Let me know if you have any other questions :-)
