Interpret the given picture and explain any one strategy to control it from becoming an ecological disaster.

The picture depicts industrial pollution causing environmental degradation, with emissions from factories contributing to air and water pollution. Strategy: Adopting Cleaner Technology: Industries should implement eco-friendly technologies and renewable energy sources to minimize pollution.
Strict Regulations: Governments must enforce stricter pollution control laws and incentivize compliance.
Public Awareness: Raising awareness about environmental conservation can encourage industries and individuals to adopt sustainable practices.
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 \(P,O,Q\).
