Area (in sq. units) of the region outside

$${{\left| x \right|} \over 2} + {{\left| y \right|} \over 3} = 1$$ and inside the ellipse $${{{x^2}} \over 4} + {{{y^2}} \over 9} = 1$$ is :
$$6\left( {4 - \pi } \right)$$
$$3\left( {4 - \pi } \right)$$
$$6\left( {\pi - 2} \right)$$
$$3\left( {\pi - 2} \right)$$

Explanation

JEE Main 2020 (Online) 2nd September Morning Slot Mathematics - Area Under The Curves Question 103 English Explanation

Area of Ellipse = $$\pi $$ab = 6$$\pi $$

$$ \therefore $$ Required area = Area of ellipse – 4 (Area of triangle OAB)

= 6$$\pi $$ - $$4\left( {{1 \over 2} \times 2 \times 3} \right)$$

= 6$$\pi $$ - 12

= $$6\left( {\pi - 2} \right)$$ sq.units
