    Let breadth = x cm.
    Length = x + 1.25
    Area of rectangle = 159
    length * breadth = 159
    x * (x + 1.25) = 159
    x^2 + 1.25x - 159 = 0

    Use Shreedhar Acharya formula to Solve the equation,
    x = 11.99 and - 13.245.
    So, Length cannot be negative.
    X = 12 cm
    Length = 12 + 1.25 = 13.25 cm.
