OG Quant Review

p. 153, #59. The perimeter of a rectangular garden is 360 feet. What is the length of the garden?
- The book says that statement "2) the difference between the length and width of the garden is 60 ft" is valid. Basically they set it up via the equation "l-w = 60"... My question is we don't know whether length or width is longer. It could also be w-l = 60... Can someone help me explain?

Thanks!

Usually we consider the length to be greater than the width; at least that's how we'd approach it at school! I am well aware that there could be an instance when the length is smaller than the width, but those are "exceptions to the rule", so to speak.

The statement is always true, so it is saying that l=60+w.
