**Topic: Double Integrals in Cartesian Coordinates**

Consider the function \( f(x, y) = x^2 e^{x^2} \) and let \( R \) be the triangle bounded by the lines \( x = 5 \), \( x = y/2 \), and \( y = x \) in the \( xy \)-plane.

### Problem (a): Expressing the Double Integral

Express the integral \( \int_R f \, dA \) as a double integral in two different ways by filling in the values for the integrals below. For one of these, it will be necessary to write the double integral as a sum of two integrals; for the other, it can be written as a single integral.

1. \[
\int_R f \, dA = \int_a^b \int_c^d f(x, y) \, dy \, dx
\]

   where \( a = 0 \), \( b = 5 \), \( c = x \), and \( d = 2x \).

2. \[
\int_R f \, dA = \int_a^b \int_c^d f(x, y) \, dx \, dy + \int_m^n \int_p^q f(x, y) \, dx \, dy
\]

   where \( a = \), \( b = \), \( c = \), \( d = \), \( m = \), \( n = \), \( p = \), and \( q = \).

### Problem (b): Evaluation of the Integral

Evaluate one of your integrals to find the value of \( \int_R f \, dA \).

\[
\int_R f \, dA = 
\]

**Instructions**: Fill in the missing limits \( a, b, c, d, m, n, p, q \) for each double integral and evaluate the integral to find the area under the curve \( f(x, y) \) over the region \( R \).
