Find the area of the shaded region of the rectangle.

The area of a rectangle is equal to the product of its length and breadth and the area of a circle is given by the formula π r², where r is the radius and π is a constant.

Answer: The area of the shaded region is 798.86 square units.

To find the area of the shaded region, we will find the area of the circle given inside the rectangle and deduct this from the area of the rectangle.

Explanation:

Area of Circle = π r² = π (8)² = 22/7 × 64 = 201.14 square units

Area of Rectangle = Length × Breadth = 50 × 20 = 1000 square units

Area of Shaded Region = Area of Rectangle - Area of Circle = 1000 - 201.14 = 798.86 square units

So, the area of the shaded region is 798.86 square units.
