KCET2018MathematicsArea Under Curves
The area bounded by the line ( y=x, x )-axis and ordinates ( x=-1 ) and ( x=2 ) is
Options
- A( 3 2 )
- B( 5 2 )
- C( 12 )
- D( 13 )
Correct answer
B. ( 5 2 )
Step-by-step solution
Given lines, ( y=x, y=0, x=-1 ) and ( x=2 ) So, required area is given by The area of shaded region [ array l = 1 2 |x|+ 1 2 2 2 = 1 2 +2= 5 2 sq. units array ]
