Answer:

i believe the last leg will be 5, because it should be a 3,4,5 triangle

you are making it bigger, and so you must multiply 3 to each side (dilate means to become wider)

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

9, 12, 15 are you triangle side lengths

To find perimeter, add them together

15 + 12 = 27

27 + 9 = 36

Your perimeter is 36

hope this helps
