**Problem 11: Variance Calculation for Independent Uniform Variables**

Suppose \(X\) and \(Y\) are independent continuous random variables uniformly distributed on the intervals \(0 \leq x \leq 2\) and \(0 \leq y \leq 4\), respectively. Compute the variance of \(\sqrt{2}X - \frac{1}{2}Y\).

**Hint:** First find the variance of \(X\) and the variance of \(Y\).
