A) 1
B) 2
C) \[2\sqrt{2}\]
D) 4
Correct Answer: B
Solution :
the given lines are \[y=x-1;y=-x-1;\] \[y=x+1\] and \[y=-x+1\] Which are two pairs of parallel lines and distance between the lines of each pair is \[\sqrt{2}\]. Also nonparallel lines are perpendicular thus lines represents a square of side \[\sqrt{2}\]. Hence, area \[={{(\sqrt{2})}^{2}}=2sq.\text{ }units.\]
