Let
W=width
L=length
---
The perimeter, P, of a rectangle is: P=2L+2W
In this problem we are given L=3W=3X so just substitute "3X" for "L" in the perimeter formula:
P = 2L + 2W
Making the substitutions L=3X and W=X:
P = 2(3X) + 2(X)
P = 6X + 2X = 8X
and that's about as far as you can take it with the information provided.
