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 racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
