Answer:

Approximately 157.08 sq. cm.

Explanation:

The Area of an Ellipse is given by the formula
$A=\pi a b$

Here 2a = 10, so a = 5

Also, 2b = 20, b = 10

Substituting these into the area formula gives us:

$A=\pi a b\\A=\pi (5)(10)\\A=50\pi\\A=157.08$

The Area is approximately 157.08 sq. cm.
