    Length = 64 cm, width = 16 cm

    Step-by-step explanation:

    Given Perimeter = 160

    Let width = x

    Length = 4x

    Hence perimeter = 2 (length) + 2 (width)

    160 = 2 (4x) + 2 (x)

    160 = 8x + 2x

    160 = 10x

    160/10 = x

    16 = x

    Hence width = 16 cm

    Put the value of x in 4x

    Length = 4 (16)

    Length = 64 cm

    Hence length = 64 cm, width = 16 cm

    length is 64 and width is 16

    Step-by-step explanation:

    all the sides added up would be 10x becuase the lenght is 4 times the width so it would be 4x+x+4x+x which would be 10x

    so do 160/10x so x = 16
