The cross-section of a wooden rod is in the shape of an ellipse with height 22 millimeters and width 8 millimeters. Determine the standard equation of the ellipse representing the outline of the cross-section assuming the ellipse is vertical and by letting the center of the section be represented by the point (0,0).

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
