    Answer:

    Length is 45cm and Breadth is 33cm

    Step-by-step explanation:

    Perimeter = 156cm

    Let the length be x

    Breadth = x-12

    Perimter = 2(l+b)

    156 = 2(x-12+x)

    156 = 2(2x-12)

    156 = 4x-24

    156+25 = 4x

    180 = 4x

    180÷4 = x

    45 = x

    Therefore, length is x = 45cm and breadth is x-12 = 45-12 = 33cm

    OUR EQUATIONS

    LENGTH = x

    BREADTH = x–12
