p =  2w + 2L
L = 3x
w = x

campbell_st · Answer

well look at the problem this way 

|dw:1438199742717:dw|

so using the area information and the area in terms of width, you can say 

$$192 = 3w^2$$

you need to solve for w as the 1st step

when you find the width, then you can find the length, and perimeter

hope it helps
