Question

Area lying between the curve y² = 4x and y = 2x is

A.

B.

C.

D.

Answer 1

The area lying between the curve, y² = 4x and y = 2x, is represented by the shaded area OBAO as

The points of intersection of these curves are O (0, 0) and A (1, 2).

We draw AC perpendicular to x-axis such that the coordinates of C are (1, 0).

∴ Area OBAO = Area (ΔOCA) – Area (OCABO)

Thus, the correct answer is B.
