    Area of shaded region = 422 cm²

    Step-by-step explanation:

    Area of rectangle = length * breadth

    = 3cm * 10cm

    = 30cm²

    Area of circle = πr²

    = 3.14 * 12²

    = 3.14 * 12cm * 12cm

    = 452.16 cm²

    Area of shaded region = Area of circle - Area of rectangle

    = (452.16 - 30) cm²

    = 422 cm²
