Detailed Solution

$\begin{array}{l} y = \{\begin{cases} 3 + (x + 1) + (x - \frac{1}{2}), & x < - 1 \\ 3 - (x + 1) + (x - \frac{1}{2}), & - 1 \leq x < \frac{1}{2} \\ 3 - (x + 1) - (x - \frac{1}{2}), & \frac{1}{2} \leq x \end{cases} \\ y = \{\begin{cases} \frac{7}{2} + 2 x, x < - 1 \\ \frac{3}{2}, & - 1 \leq x < \frac{1}{2} \\ \frac{5}{2} - 2 x, & \frac{1}{2} \leq x \end{cases} \end{array}$

Area bounded = ar CDE + ar BCEF + ar ABF

$\begin{array}{l} = \frac{1}{2} (\frac{3}{4}) (\frac{3}{2}) + (\frac{3}{2}) (\frac{3}{2}) + \frac{1}{2} (\frac{3}{4}) (\frac{3}{2}) \\ = \frac{27}{8} sq. units. \end{array}$
