Always ensure that the operands in concatenation operations are of the same data type. Use str() to convert integers to strings if needed.
print("A"*3)
print(5*3)
print("15" + 3)
print("15" + "13")
"A"*3 repeats the string "A" three times, resulting in "AAA".5*3 performs integer multiplication, resulting in 15."15" + "13" concatenates two strings, resulting in "1513"."15" + 3 raises a TypeError because Python does not allow concatenation of a string ("15") and an integer (3).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 \(P,O,Q\).
