Statement I The area of region bounded parabola $y^{2}=4 x$ and $x^{2}=4 y$ is $\frac{32}{3}$ sq units. Statement II The area of region bounded by parabola $y^{2}=4 a x$ and $x^{2}=4 b y$ is $\frac{16}{3} a b$

Key Concepts

Definite Integration for Area Calculation

Calculating the area enclosed by curves typically requires setting up and evaluating definite integrals. Once the correct bounds of integration are determined from the intersection points, the area is obtained by integrating the difference between the functions that describe the upper and lower boundaries of the region.

Conic Sections - Parabolas

A parabola is a fundamental conic section defined by a quadratic relation between its coordinates. In these problems, the parabolas open in different directions, and understanding their geometry, such as the vertex, focus, and axis of symmetry, is crucial for visualizing the bounded region and setting up the appropriate area integrals.

Intersection of Curves

Finding the common points where the curves intersect is essential because these intersection points serve as the limits of integration when calculating the area between the curves. This involves solving the system of equations corresponding to the curves, which may involve substitution or elimination methods.

Scaling with Parameters

Introducing parameters into the equations of curves, such as a and b in the generalized parabola equations, alters the size and shape of the curves. Understanding how these parameters affect the equations enables one to generalize area calculations and determine how the area scales with these parameter values.
