The area of the parallelogram whose adjacent sides are ( i + k ) and ( 2 i + j + k ) is
Options
- A( ( 2 )
- B( 3 )
- C( 13 )
- D( 04 )
Correct answer
B. ( 3 )
Step-by-step solution
Given sides of parallelogram, [ array l a = i + k b =2 i + j + k array ] So, area is given by ( | a b | ) [ | array lll i & j & k 1 & 0 & 1 2 & 1 & 1 array |=- i + j + k ] Therefore, area of parallelogram, is ( 1+1+1 = 3 )
