Winter wheat. While finding the amount of seed needed to plant his three square wheat fields. Hank observed that the side of one field was 1 kilometer longer than the side of the smallest field and that the side of the largest field was 3 kilometers longer that the side of the smallest field. If the total area of the three fields is 38 square kilometers, then what is the area of each field?
