A cold storage plant is a facility used to store perishable food items like fruits, vegetables, meat, fish, and dairy products at low temperatures.
The main components shown in the layout are:
1. Compressor: Compresses the refrigerant to high pressure.
2. Condenser: Removes heat from the refrigerant and converts it to liquid.
3. Receiver: Stores liquid refrigerant.
4. Expansion valve: Reduces the refrigerant pressure before entering the evaporator.
5. Evaporator: Absorbs heat from the cold storage room, keeping it cool.
6. Cold storage chamber: The insulated space where goods are stored.
7. Fans: Circulate cold air evenly inside the storage room.
A labelled diagram should show all these components connected in the correct sequence.
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 \(P,O,Q\).
