The equation of the ellipse is given by:
\[
\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1.
\]
To find the area of the region bounded by the ellipse, we use the formula for the area of an ellipse:
\[
A = \pi \cdot a \cdot b.
\]
This is the standard result for the area of an ellipse, where \( a \) and \( b \) are the semi-major and semi-minor axes, respectively.
Conclusion:
The area of the region bounded by the ellipse is:
\[
\boxed{A = \pi \cdot a \cdot b}.
\]
