    Two pieces will equal 16 and 32 centimeters long

    16/4 = 4 centimeters each side perimeter

    4*4 = 16 square centimeters area

    32/4 = 8 centimeters each side perimeter

    8*8 = 64 square centimeters area

    It should be cut into pieces 16 cm long and 32 cm long. The area of the square with the 16cm perimeter would be 16.[(16/4)^2]. The area of the square with the 32cm perimeter would be 64. [(32/4)^2].

    Admittedly I just used the guess and check method. Sorry I couldn't give you a formula or anything.

    I think you start with

    x^2 + y^2 = 80

    4x + 4y = 48

    Does this help get you started?
