Options
- Azero
- B( 1 3 )
- C( 2 3 )
- D1
Correct answer
C. ( 2 3 )
Step-by-step solution
The area of the region bounded by the curve (y=f(x) ) and the ordinates (x=a, x=b ) is given by ( Area = | _a^b y d x | ) According to the question, (y=x|x|= cases x^2, & x 0 -x^2, & x Required area (= ) area of region ( OAB + ) area of region ( OCD ) (=2 ) Area of region ( OAB ) (=2 ₀^1 x^2 d x= 2 3 s q ). units
