The area of the shaded region is [(169π/4)-60]m².
- The length of the rectangle is 12 m.
- The breadth of the rectangle is 5 m.
- The area of the rectangle = length * breadth.
- The area of the rectangle = 12 * 5
- The area of the rectangle = 60m²
- Let h be the diagonal of the rectangle.
- Using the Pythagorean theorem,
- h² = 12² + 5²
- h² = 144 + 25
- h² = 169
- h = √169
- h = 13
- The diagonal of the rectangle is also the diameter of the circle.
- Let r be the radius of the circle.
- 2r = 13
- r = 13/2m
- The area of the circle is πr².
- The area of the circle = π(13/2)²
- The area of the circle = (169π/4)m²
- The area of the shaded region equals the area of the circle minus the area of the rectangle.
- The area of the shaded region = [(169π/4) - 60]m²

Answer:
The percentage of error in the question is 75%.
Step-by-step explanation:
To find the percentage of error, we need to subtract the actual value from the value that was expected, divide the result by the expected value.
He predicted that the crop would produce 8 bushels so this is our expected value. The actual value, which is the number of bushels produced, is 14.
- If we make the calculation (14 - 8) / 8 = 6 / 8.
- And then multiply the result by 100 to find the percentage, (6 / 8) x 100 = 75.
So the percentage of error in the question is 75%.
