when both \left|2x+y \right| & \left|x-2y \right| is +ve then the line becums 3x-yâ‰¤4...
When \left|2x+y \right| is +ve but \left|x-2y \right| is -ve then line becums x+3yâ‰¤4...

solve get the point of intersection by drawing the lines and find the reqd area of a the quad..
atleast i think this is the way to solve this 1 :P
