1. **Identify the midpoints and centroid**: Given that \(D, E,\) and \(F\) are the midpoints of \(BC, CA,\) and \(AB\) respectively, and \(G\) is the intersection of \(DF\) and \(BE\), we know that \(G\) is the centroid of \(\triangle ABC\). The centroid divides each median into a ratio of \(2:1\).

2. **Area of \(\triangle ABE\)**: Since \(E\) is the midpoint of \(CA\), \(\triangle ABE\) is half of \(\triangle ABC\). Therefore, the area of \(\triangle ABE\) is:
   \[
   \text{Area of } \triangle ABE = \frac{1}{2} \times \text{Area of } \triangle ABC = \frac{1}{2} \times 64 = 32
   \]

3. **Area of \(\triangle AFG\)**: Since \(F\) and \(G\) are midpoints, \(\triangle AFG\) is similar to \(\triangle ABE\) and is scaled down by a factor of \(\frac{1}{2}\). Therefore, the area of \(\triangle AFG\) is:
   \[
   \text{Area of } \triangle AFG = \frac{1}{4} \times \text{Area of } \triangle ABE = \frac{1}{4} \times 32 = 8
   \]

4. **Area of \(\triangle GBE\)**: Since \(G\) is the centroid, it divides \(\triangle ABE\) into three smaller triangles of equal area. Therefore, the area of \(\triangle GBE\) is:
   \[
   \text{Area of } \triangle GBE = \frac{1}{3} \times \text{Area of } \triangle ABE = \frac{1}{3} \times 32 = \frac{32}{3}
   \]

5. **Area of quadrilateral \(AFGE\)**: The area of quadrilateral \(AFGE\) is the area of \(\triangle ABE\) minus the area of \(\triangle GBE\):
   \[
   \text{Area of } AFGE = \text{Area of } \triangle ABE - \text{Area of } \triangle GBE = 32 - \frac{32}{3} = \frac{96}{3} - \frac{32}{3} = \frac{64}{3}
   \]

The final answer is \(\boxed{\frac{64}{3}}\).
