## Question

### Solution

Correct option is

2 sq. units

We have,   Thus, the lines given by equation (i) are Clearly, these two equations represent a pair of perpendicular lines intersecting at (0, 1). The equations of the angle bisectors are y = 1 and x= 0.

The line x + y = 3 forms the triangle ABC with the two angle bisectors.  #### SIMILAR QUESTIONS
