    Answer: 128.86cm²

    Step-by-step explanation:

    The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.

    Area of the rectangle = 11 x 12

    = 132cm²

    Area of the circle with radius of 1cm = πr²

    = 3.142 x 1²

    = 3.142cm²

    Therefore, area of the shaded region = 132cm² - 3.142cm²

    = 128.86cm²
