Question:

The area bounded between the parabola x2 = \(\frac{y}{4}\) and x2 = 9y and the straight line y = 2 is : 

Options:

\(\frac{20\sqrt{2}}{3}\)

10\(\sqrt{2}\)

20\(\sqrt{2}\)

\(\frac{10\sqrt{2}}{3}\)

Correct Answer:

\(\frac{20\sqrt{2}}{3}\)

Explanation:

Area = 2\(\int_{0}^{2}(3\sqrt{y}-\frac{1}{2}\sqrt{y}) dy\)

        = \(\frac{20\sqrt{2}}{3}\)
