Right to choose/Right to be assured: The consumer has the freedom to access a variety of products at competitive prices. This implies that the marketers should offer a wide variety of products in terms of quality, brand, prices, size, etc., and allow the consumer to make a choice from among these.
Right to be heard: The consumer has a right to file a complaint and to be heard in case of dissatisfaction with a good or a service. It is because of this reason that many enlightened business firms have set up their own consumer service and grievance cells.
Right to safety: The consumer has a right to be protected against goods and services that are hazardous to life, health, and property. Thus, consumers are educated that they should use electrical appliances that are ISI marked, as this would be an assurance of such products meeting quality specifications.
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 \(P,O,Q\).
