Find the area of the shaded region of a rectangle
Question: Find the area of the shaded region of a rectangle.
Answer: (16 π - 100) square units
We will use the formula of the area of a circle to find the area of the circle inside the rectangle and deduct its area from the area of the rectangle.
Area of Circle = π r2 = π (8)2 = 16 π square units
Area of Rectangle = Length × Breadth = 50 × 20 = 100 square units
Area of Shaded Region = Area of Rectangle - Area of Circle = (16 π - 100) square units
