Mathematics - Area Under Curves Question with Solution | TestHub

A point $\mathrm{P}(\mathrm{x},\mathrm{y})$ moves is such a way that $[\mathrm{x}+\mathrm{y}+1]=[\mathrm{x}]$ (where [.] greatest integer function) and $\mathrm{x}\in (0,2)$. Then the area representing all the possible positions of P equals
