Hi,

Plot the three lines and find out the intersection points.
The three intersection points are (2,0), (1,1), (3,1)
The bounded area is a triangle.

So use the determinent method to find the area.
Put the values in a 3x3 determinent and take the third row as 1 for every column.
Solve the determinent and divide the value by 2. That will be ur answer.
