We know that L = 4W, and P = 2l + 2w, so 150 = 2L + 2w
So, 150 = 2*4w + 2w
      150 = 8w + 2w
      150 = 10w
       w = 150/10
       w=15
So, the Width of the Rectangle is 15 feet.
And if they asked you to find the length,
 L = 4W
L = 4*15
L=60 
so, the Length will be 60 feet.

Hope this Helps! :)
Let width be x So 2(x+4x)=10x=150 x = 15 feet
