It Is Desired to Make a Rectangular Pen with Diameter

question 198

Short Answer

It is desired to make a rectangular pen with diameter equal to 40 feet. It is not necessary, however, to achieve maximum area. In fact, any area that is greater than or equal to 75% of the maximum area will be satisfactory. Under these conditions, find the maximum acceptable length of the longer side.
