Best ResponseYou've already chosen the best response.0or does it have to be less than 49

Best ResponseYou've already chosen the best response.0no it doesn't have to be less than 49 i don't think. you just must have LW = 49 so at least in theory L could be say 1,000,000 making W \[\frac{49}{1000000}\]

Best ResponseYou've already chosen the best response.0your perimeter in this problem is not fixed. if it was then you would have a restriction on L
