Answer:

Area of the shaded region=
$128.86\,cm^2$

Explanation:

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

Area of rectangle=
Length* Width

$Length=11\,cm\\Width=12\,cm$

Area is:

$=11* 12\\\\=132\,cm^2$

Area of the circle =
$\pi * r^2$

$r=1\,cm$

As,
$\pi =(22)/(7) =3.14$

Area of the Circle is :

$=3.14* 1 * 1\\\\=3.14* 1\\\\=3.14\,cm^2$

Area of the Shaded region:

Area of the shaded region
$=132-3.14\\\\=128.86\,cm^2$
