What is the area of a section bounded by a closed elliptical figure whose major and minor segments measure 60 m and 40 m, respectively?

no solid mensuration here. Just regular plane geometry.
The area of an ellipse with semiaxes a and b is πab.
Note that if a=b, we have a circle of radius a, and area πa^2 
a is 60m while b is 40m. then divide both 60m and 40m in to two so 60/2 and 40/2 the area is (pie)(30)(20) so the area is 1884.96m^2
