The Correct Option is C

Solution and Explanation

Required area $=$ Area of shaded region $OAB$
$={ }_{0}^{2} ydx ={ }_{0}^{2} xdx =\frac{ x ^{2}}{2}_{0}^2$
$=2$ sq unit
Alternate Solution
Required area $=$ Area of $\triangle OAB$
$=\frac{1}{2} \times 2 \times 2$
$=2 \,sq$ unit

Area between Two Curves

Integral calculus is the method that can be used to calculate the area between two curves that fall in between two intersecting curves. Similarly, we can use integration to find the area under two curves where we know the equation of two curves and their intersection points. In the given image, we have two functions f(x) and g(x) where we need to find the area between these two curves given in the shaded portion.

Area Between Two Curves With Respect to Y is

If f(y) and g(y) are continuous on [c, d] and g(y) < f(y) for all y in [c, d], then,
