A questionnaire for a field visit to a factory should include questions related to operations, safety, production, and management. Sample questions:
What are the main products manufactured in this factory?
What raw materials are used in the production process?
How many workers are employed in this factory?
What safety measures are followed in the workplace?
What are the working hours and shift patterns?
How is waste managed and disposed of?
What machinery and technology are used in the factory?
What quality control measures are taken?
\[ {\text{A well-structured questionnaire helps in effective data collection.}} \]
In the following figure \(\triangle\) ABC, B-D-C and BD = 7, BC = 20, then find \(\frac{A(\triangle ABD)}{A(\triangle ABC)}\). 
The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\)) 
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
