Area under the curveHard

Question

The area (in square units) bounded by the curves y = √x, 2y - x + 3 = 0, x-axis and lying in the first quadrant is :

Options

A.9
B.36
C.18
D.

Solution


                

intersection point
⇒ x - 2√x - 3 = 0
√x = 3, - 1 ⇒ x = 9
Required Area - area of ᐃ ABC

= 18 - 9 = 9
