This refers to the large-scale cultivation of flowering plants and cut flowers primarily for sale in the market. It focuses on producing high-quality flowers in quantities sufficient to meet commercial demand. It involves activities like propagation, growing, harvesting, processing, and marketing of flowers and ornamental plants.
This involves the use of advanced technologies and modern scientific methods in the production of flowers. Techniques such as protected cultivation (greenhouses, polyhouses), use of automated irrigation, climate control, use of growth regulators, and tissue culture are part of hi-tech floriculture to increase yield, quality, and efficiency.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
