1. The problem statement, all variables and given/known data Find the dimensions of of the rectangle with perimeter 200 meters that has the largest area. 2. Relevant equations 3. The attempt at a solution This is in the section on Global Maxima/Minima so I know it has to be something with graphing a formula and finding the maxima, but I cannot figure where to start on this. The book is no help (Applied Calculus - Hughes-Hallett, et.al) and this is not the first time it has presented problems that it does not even began to describe in the text. :grumpy: Can someone tell me where to start?
