Find the area of the region bounded by the ellipse `x^2/4 + y^2/9 = 1`
The given equation of the ellipse can be represented as
It can be observed that the ellipse is symmetrical about x-axis and y-axis.
∴ Area bounded by ellipse = 4 × Area OAB
Therefore, area bounded by the ellipse = `4 xx (3pi)/2 = 6pi` units
