The story definitely reminds one of “Birth’ by A. J. Cronin. There is a striking similarity between both the stories. Both revolve around doctors who try their level best to save the lives of nearly dead human beings. In the story ‘Birth’, Dr Andrew saves the life of an almost still born baby boy with a lot of effort, while ‘The Enemy’ deals with the story of Dr Sadao who saves an American soldier from the enemy troops during the times of war. Both the stories deal with humanity, love, affection, selflessness and a strong sense of duty.
How did Dr. Sadao plan the American prisoner’s escape? (The Enemy)
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 \(P,O,Q\).
