# Find the area of

Given the boundaries of the area to be found are,

• The parabola y2 = 4x

• x = 3 (a line parallel toy-axis) As per the given boundaries,

• The curve y2 =4x with vertex at (0,0), has only the positive numbers as y has even power, so it is about the x-axis equally distributed on both sides.

• x= 3 are parallel toy-axis at 3 units from the y-axis.

• The boundaries of the region to be found are,

Point A, where the curve y2 = 4x and x=3 meet when y is positive.

Point B, where the curve y2 = 4x and x=3 meet when y is negative.

Point C, where the x-axis and x=3 meet i.e. C(3,0).

Point O, the origin.

Area of the required region = Area of OAB

Area of OAB = Area of OAC + Area of OBC.

[area under OAC = area under OBC as the curve y2 = 4x is symmetric]

Area of OAB = 2 × Area of OAC  [Using the formula ] The Area of the required region Rate this question :
