Ok... after much confusion, I've come to the conclusion that you must have written the question wrong and it's actually the perimeter that is 90 feet so that's how I'm going to work it...
Width = w Length = 4w - 9
P = 2w x 2L 90 = 2w + 2(4w - 9) 90 = 2w + 8w - 18 90 = 10w - 18 108 = 10w 108/10 = w 10 4/5 = w
Width is 10 4/5 ft
Length = 4w - 9 L = 4(10 4/5) - 9 L = 43 1/5 - 9 L = 34 1/5 ft
Length 34 1/5 ft Width 10 4/5 ft or Length 34.2 ft and width 10.8 ft
The man is envious because he's jealous of the dog's fur. For he has natural covering and is kept warm because of it. The man has to wear several layers of clothing to be warm while the dog is warm enough with his fur/natural covering.
