Q3: [ Note The given parameters are length F and posint N .] A farmer has F feet of fencing with which he wishes to fence in a rectangular area, of some width w and depth d (for you to determine), and which is divided into N pens parallel to the width side. (So each pen has width w .) Let A N ( w ) denote the area of the big rectangle as a function of width. Compute this function: A N ( w ) = . Let w N and d N be the dimensions which maximize total area. Then w N = . Let α N denote the maximum area w N · d N Then lim N →∞ α N = . Q3:
