    Answer:

    Width = 7 units

    Step-by-step explanation:

    Length = x units

    Width = (x -1) units

    Area = 56 square units

    length * width = 56

    x * (x – 1) = 56

    x*x – x*1 = 56

    x² – x  – 56 = 0

    x² -8x + 7x – 7*8 = 0

    x(x – 8) + 7(x – 8) = 0

    (x – 8)(x + 7) = 0

    Here, (x +7) is ignored because measurement will not  in negative.

    x – 8 = 0

    x = 8

    Length =  8 units

    Width = 8-1 = 7 units

    Width
