HACTEHA [7]

Answer:

119.43cm^2

Step-by-step explanation:

The computation of the area of the shaded region is shown below:

As we know that

= Area of the rectangle - Area of the circle

where,

Area of rectangle is

= length \times breadth

= 11\times 12

= 132 cm^2

And, the area of the circle is

=  \pi\times r^2\\\\ = \frac{22}{7} \times 2^2\\\\ = \frac{88}{7} cm^2

Now the area of the shaded region is

= 132 cm^2- \frac{88}{7}cm^2

= 119.43cm^2

We simply deduct the area of the circle from the area of the rectangle so that the area of the shaded region.
