Answer:

Step-by-step explanation:
Given equation of ellipsoids,

The vector normal to the given equation of ellipsoid will be given by





Hence, the unit normal vector can be given by,



Hence, the unit vector normal to each point of the given ellipsoid surface is

For the lateral area, don't include the base area. For the surface area, you should include it.
