Hello

I could do with a hint or two for this one:

An squared area is to be bounded by using two types of fences. Two parallel flanks of the area will be bounded using a fence that cost \$60 per meter, while the other two will be bounded with a fence that cost \$50 per meter. What is the area with the maximal size which we can bound like this, so that our total expense will be \$6000 ?

Thanks !
