    Step-by-step explanation:

    i) Length = 2.3 cm

    Width = 19 mm = 19/10 = 1.9cm {10mm = 1 cm}

    Area of rectangle = length * width

    = 2.3*1.9

    = 4.37 cm²

    ii) Length = 2.3 cm = 2.3*10 = 23 mm

    Width = 19mm

    Area of rectangle = length * width

    = 23 * 19

    = 437 mm²
