    W = 14 inches

    Step-by-step explanation:

    Perimeter of a rectangle

    = 2 (L + W)

    Where

    L = length

    W = width

    Given

    Perimeter = 84 inches and

    Length = 28 inches

    Width = ?

    Therefore,

    84 = 2 (28 + W)

    Expand the bracket

    84 = 2 x 28 + 2 x w

    84 = 56 + 2w

    Subtract 56 from both sides

    84 - 56 = 56 - 56 + 2w

    28 = 2w

    Divide both sides by 2

    28/2 = w

    W = 14 inches

    The width of the rectangle is 14 inches
