![**Problem Statement:**
Use the change of variables \( s = x + y, \, t = y \) to find the area of the ellipse \( x^2 + 2xy + 2y^2 \leq 1 \).
**Solution:**
Here, you are tasked with calculating the area of an ellipse defined by the equation \( x^2 + 2xy + 2y^2 \leq 1 \). To do this, you need to implement a change of variables: \( s = x + y \) and \( t = y \). By substituting these into the ellipse equation, you can transform and simplify the problem to perform the integration needed for area calculation.
Area = \[\underline{\quad \quad \quad \quad}\]
(Note: Detailed steps and calculations should follow to complete the solution, showing how to apply the change of variables and perform the integration.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F18fe6d10-65c6-4dea-a463-83c487832ab0%2Fd187d260-de6b-418e-8f9f-c829b8feaf56%2F8l9giry_processed.png&w=3840&q=75)
