    Answer:

    5.12×10⁹ and 1.024×10¹¹

    Step-by-step explanation:

    area of rectangle 1 :

    (3.2 × 10⁵)(1.6 × 10⁴) = (3.2×1.6)(10⁵×10⁴)

    =5.12× (10^5+4)

    =5.12×10⁹

    area of rectangle 2 :

    (1.28×10⁷)(8×10³) = (1.28×8)(10⁷×10³)

    = 10.24×(10^7+3)

    = 10.24×10¹⁰

    =1.024×10¹¹
