1. **Identify Upper and Lower Curves**: On the interval $(0, 1)$, $x \ge x^2$. So $y=x$ is the upper curve and $y=x^2$ is the lower curve.
2. **Setup Area Integral**: $Area = \int_0^1 (Upper - Lower) \, dx = \int_0^1 (x - x^2) \, dx$.
3. **Antiderivative**: $[\frac{x^2}{2} - \frac{x^3}{3}]_0^1$
4. **Evaluate**:
   - $(\frac{1}{2} - \frac{1}{3}) - (0 - 0)$
   - $= \frac{3-2}{6} = 1/6$.
5. **Result**: 1/6 square units.
