    Let the width be x.

    Width = x

    Length = 4x

    Perimeter = 2 (Length + Width)

    Perimeter = 2 (x + 4x)

    Perimeter = 2 (5x)

    Perimeter = 10x

    Given that perimeter = 50 m

    10x = 50 m

    x = 5m

    Width = x = 5m

    Length = 4x = 4 x 5 = 20 m

    Answer: The dimension of the room is 5m by 20 m
