Q. The area bounded by the curve $y = \frac{1}{2}x^{2}$, the $x$-axis and the ordinate $x = 2$ is

A) $\frac{1}{3}\ sq\ units\$
B) $\frac{2}{3}sq\ units\$
C) $1\ sq\ units\$
D) $\frac{4}{3}\ sq\ units\$
Explanation

(d)
$Required\ area = \int_{0}^{2}{y\ \ dx}$

$= \int_{0}^{2}{\frac{x^{2}}{2}dx = \left\lbrack \frac{x^{3}}{6} \right\rbrack_{0}^{2} = \frac{4}{3}\ sq\ units}$
