    Answer:

    Here

    Step-by-step explanation:

    length = x

    width = 2x – 3

     

    Perimeter = 2length + 2 width

    2x + 2(2x – 3) = 42

    2x + 4x – 6 =42

    6x – 6 = 42

    Add 6 to both sides

    6x = 48

    Divide both sides by 6

    x = 8

     

    Length = 8 inches

    Width = 2(8) – 3 = 16-3 = 13 inches
