    We call : → l = lenght

    We know the perimeter of the

    w = width the rectangle : P = 2 (w+l)

    P = perimeter

    P = 2 (w+l) but l = w+2

    56 = 2 (w+w+2)

    56 = 2 (2w+2)

    56 = 4w + 4

    4w = 56 - 4

    4w = 52 l = w + 2

    w = 52 : 4 l = 13 + 2

    w = 13 cm l = 15 cm

    P = 56 = 2l + 2w and l=2+w

    56 = 2 (2+w) + 2w

    56 = 4 + 2w + 2w

    52 = 4w

    w = 13 cm

    l = 13+2

    l = 15 cm
