What's the area of an ellipse with the major axis 20 m and the minor axis 10 m?
-----------
Area = pi*a*b where a & b are the semi-minor * semi-major axes.
--> pi*10*5

The area of an ellipse if found by

where a and b are semi-major and semi-minor axes...thus
A = pi * 10 * 5 = 157 (or so)
Choice B.
