Areas between curves

Do you mean $x- 2y^2\ge 0$ and $1- x- |y|\ge 0$?
Draw graphs of the corresponding equations. $x- 2y^2= 0$ is the same as $x= 2y^2$, a hyperbola with horizontal axis. 1- x- |y|= 0 is the same as x= 1-|y|, a "broken" line or a "V" opening to the right. Then take one point on each side of the curve to decide which side is "$\ge$" and which is "$\le$.
