Question
**Problem Statement:**

Evaluate the double integral 

\[
\iint_R e^{x+y} \, dA
\]

where \( R \) is given by \( |x| + |y| \leq 1 \).

**Explanation:**

- The integral \(\iint_R e^{x+y} \, dA\) represents the evaluation of the exponential function \(e^{x+y}\) over a specific region \(R\).
- The region \(R\) is defined by the inequality \( |x| + |y| \leq 1 \).
- This describes a diamond-shaped region centered at the origin on the xy-plane, bounded by the lines \(x + y = 1\), \(x + y = -1\), \(x - y = 1\), and \(-x + y = 1\).
