Given that center is at origin that is (0,0)
x intercepts are + 10 and -10 so the right most and left most points are ( 10,0) and (-10,0)
the y intercepts are + 5 and -5 so the top most point is (0,5 ) and bottom most point is ( 0,-5 )
now we find half of major length ( which is along x axis here )= (10+10 )/2=10
and half of minor length ( which is along y axis here )= (5+5)/2 = 5
hence equation of ellipse : ( X - 0 ) ^2 + ( Y -0 )^2
-------------- -----------
10 ^2 5 ^2

I believe Tom needs 20 posts, and the dimensions of the fence are 42’ length, by 18’ width. If you’re looking for the area it’s 756 ft sq.
