A farmer has 120 ft. of fencing available to enclose 2 adjacent rectangular pens alongside his barn. NO fencing is required along the bard side. He needs to have a total of 930 sq.ft. Determine the width (x) and the combined length of the pens. There are two solutions. One is 29.49 ft, 31.53 ft. What is the other one? Enter width ft, length ft.
