    area of first = length1 x width
    15 = length1 x width
    width = 15/length1

    area of 2nd:
    16 = length2 x width
    width = 16/length2

    so length2/length1 = 16/15

    the length of the first is 15, its width is 1
    the length of the 2nd is 16, its width is 1

    the largest value of the width has to be 1
