Question -

Area lying between thecurve y2 = 4x and y =2x is

A. 

B. 

C. 

D. 



Answer -

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

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

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

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

 square units

 

Thus, the correct answeris B.
