The area of the region bounded by the lines ( y=m x, x=1, x=2 ), and ( x ) axis is ( 6 ) sq. units, then ' ( m ) ' is
Options
- A( 11 )
- B( 04 )
- C( 13 )
- D( 12 )
Correct answer
B. ( 04 )
Step-by-step solution
Given that, equation of line ( y=m x, x=1 ) and ( x=2 ) So, required area is given by [ array l Area = ₁² m x d x=6 [m x² 2 ]₁²=6 m (2²-1² )=12 3 m=12 m=4 array ]
