Options
- A8 3 sq. units
- B5 8 sq. units
- C3 8 sq. units
- D3 5 sq. units
Correct answer
A. 8 3 sq. units
Step-by-step solution
Refer figure, point of intersection of given curves are x ^2=4 x x ( x -4)=0 O (0,0) and P (4,4) Required area is shaded. aligned & A= ₀^4( 4 x -x) d x=2 ₀^4 x^ 1 2 d x- ₀^4 x d x & =2 [ x^ 3 2 ( 3 2 ) ]₀^4- [ x^2 2 ]₀^4- ( 4 3 )(4 2)- 16 2 & = 32 3 - 16 2 = 16 6 = 8 3 sq. units. aligned
