Since the maximum amount of siding for a set amount of money would be obtained by getting as little cedar as possible but (since the cedar side is given to be a 'length' side which implies it cannot be shorter than a 'width' side), the maximum would be a perfectly square garden. Therefore, if X is the length of one side,

10X + (3*5)X = 225 -> 25X = 225 -> X = 9

So, the area enclosed would be 9*9 or 81 m
