Resizing a chart refers to adjusting the dimensions (height and width) of a chart within a document or a spreadsheet. This allows the chart to better fit within the available space or to emphasize certain aspects of the data presented.
To resize a chart:
- Click on the chart to select it.
- Drag the corner or edge of the chart to adjust its size.
- Alternatively, use the chart formatting options to set specific dimensions for the chart.
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 \(P,O,Q\).
