Positive Consequences: Population growth was controlled, reducing strain on resources. Families could allocate more resources like education and healthcare to a single child.
Negative Consequences:
Aging Population: The population aged rapidly, leading to labor shortages.
Gender Imbalance: A preference for male children resulted in a skewed gender ratio.
Social Issues: Increased pressure on single children, leading to psychological problems.
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 \(P,O,Q\).
