    Let us assume the width of the rectangular room = x feet

    then

    Length of the rectangular room = x + 4 feet

    Perimeter of the rectangular room = 38 feet

    Then

    Perimeter of the rectangular room = 2 (length + Width)

    38 = 2 [x + (x + 4) ]

    38 = 2 (2x + 4)

    38/2 = 2x + 4

    19 = 2x + 4

    19 - 4 = 2x

    15 = 2x

    x = 15/2

    = 7.5 feet

    So the length of the rectangular room is 7.5 feet.
