Question Details

Area bounded by the ellipse x²/4 + y²/9 = 1 is

Options

A

6π sq. units

B

12π sq. units

C

3π sq. units

D

None of these

Correct Answer :

6π sq. units

Solution :

The correct option is 6π sq. units.

To find the area bounded by the ellipse, we start with the standard equation of an ellipse:
x2 a2 + y2 b2 = 1
where a is the semi-major axis (or semi-minor axis depending on the values) and b is the semi-minor axis (or semi-major axis).

The given equation of the ellipse is:
x2 4 + y2 9 = 1
Comparing this with the standard equation, we get:
a2 = 4 which gives a = 2
and
b2 = 9 which gives b = 3 .

The standard formula for the total area A enclosed by the ellipse is:
A = π · a · b

Substituting the values of a and b into the formula:
A = π × 2 × 3
A = 6 π  sq. units

Thus, the area bounded by the given ellipse is indeed 6π sq. units.
