Answer:
Approximately 157.08 sq. cm.
Step-by-step explanation:
The Area of an Ellipse is given by the formula [tex]A=\pi a b[/tex]
Here 2a = 10, so a = 5
Also, 2b = 20, b = 10
Substituting these into the area formula gives us:
[tex]A=\pi a b\\A=\pi (5)(10)\\A=50\pi\\A=157.08[/tex]
The Area is approximately 157.08 sq. cm.
