Two-Thousand-Year-Old Problem Find the area of two fields, given that one field yields 2/3 of a bushel of wheat per square yard and the other yields 1/2 a bushel per square0 yard. The total area of the two fields is 1,800 square yards and the total yield is 1, 100 bushels. (This is a typical Babylonian problem, as mentioned in the historical, with modernized units of measure.)
