(i) Patents - Non-current Assets (Intangible Assets)
(ii) Capital Reserve - Shareholders’ Funds (Reserves and Surplus)
(iii) Prepaid Rent - Current Assets (Other Current Assets) Patents, as intangible assets, fall under Non-current Assets.
Capital Reserve is part of Reserves and Surplus under Shareholders’ Funds. Prepaid Rent, being a short-term asset, falls under Current Assets as Other Current Assets.
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 \(P,O,Q\).
