Exp. (c)Given Two parabolas x2=4y​ and x2=9yTo find The area bounded between the parabolas and the straight line y=2.The required area is equal to the shaded region in the drawn figure.The area of the shaded region (which can be very easily found by using integration) is twice the area shaded in first quadrant.∴ Required area=2∫02​(3y​−2y​​)dy=2∫02​(25​y​)dy=5(3/2y3/2​)02​=310​(23/2−0)=3202​​
