The statement "All consumption goods are durable in nature" is false.
- Durable Goods:
These are goods that have a long life span, and can be used repeatedly over an extended period of time, such as cars, appliances, and furniture.
- Non-Durable Goods: These are goods that are consumed immediately or within a short period of time, and are used up in a single or few uses, such as food, beverages, and toiletries. While durable goods are part of consumption, many consumption goods are non-durable. For instance, when people purchase groceries or clothing, these items are consumed or used up in a short period.
Therefore, not all consumption goods are durable.

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 \(P,O,Q\).
