Let function f(x) is defined in $\left[-2,2\right]$ as $f\left(x\right)=\{\begin{array}{cc}\left\{x\right\}\text{,}& -2\le x\le -1\\ \left|sgnx\right|\text{,}& -1\le x\le 1\\ \left\{-x\right\}\text{,}& 1<x\le 2\end{array}$ where {x} and sgn x denotes fractional part and signum functions, respectively. Then the area bounded by the graph of f(x) and x-axis is
