Question 1: Find the area of the region bounded by the ellipse
ANSWER :  The given equation of the ellipse, , can be represented as
It can be observed that the ellipse is symmetrical about xaxis and yaxis.
∴ Area bounded by ellipse = 4 × Area of OAB
Therefore, area bounded by the ellipse = 4 × 3π = 12π units
Question 2: Find the area of the region bounded by the ellipse
ANSWER : The given equation of the ellipse can be represented as
It can be observed that the ellipse is symmetrical about xaxis and yaxis.
∴ Area bounded by ellipse = 4 × Area OAB
Therefore, area bounded by the ellipse =
Question 3: Area lying in the first quadrant and bounded by the circle x^{2} + y^{2} = 4 and the lines x = 0 and x = 2 is
A. π
B.
C.
D.
ANSWER : The area bounded by the circle and the lines, x = 0 and x = 2, in the first quadrant is represented as
Thus, the correct answer is A.
Question 4: Area of the region bounded by the curve y^{2} = 4x, yaxis and the line y = 3 is
A. 2
B.
C.
D.
ANSWER :  The area bounded by the curve, y^{2} = 4x, yaxis, and y = 3 is represented as
Thus, the correct answer is B.
