    Perimeter = 2( Length) + 2 ( Width )
    Perimter = 56 m
    56 = 2( Length) + 2 ( Width )
    Length = 3x
    Width = x
    56 = 2( 3x ) + 2 ( x )
    56 = 6x + 2x
    56 = 8x
    7 = x

    Length = 3x
    Width = x
    Length = 3(7)
    Width = 7
    Length = 21
    Width = 7

    Checking
    Perimeter = 2( Length) + 2 ( Width )
    Perimeter = 2( 21 ) + 2 ( 7 )
    Perimeter = 42 + 14
    Perimeter = 56m Yes
