Data formatting refers to the process of arranging or structuring data in a specific format for better presentation and readability. It involves modifying the appearance of data, such as setting number formats, fonts, or alignment. Tools used to format data include:
1. Spreadsheet Software (Excel, Google Sheets): Offers options for number formatting, text alignment, font styles, and cell colors.
2. Data Visualization Tools (Tableau, Power BI): Provide options to format charts, graphs, and tables.
3. Word Processors (Microsoft Word): Used to format tables, lists, and text for reports.
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 \(P,O,Q\).
