that would be specific to the object involved. for example, if you needed to find the surface area of the inside of a cylinder in an engine, i could help you find out how much that cylinder can displace, helping you find horsepower for that cylinder. then you could multiply that number by the number of cylinders the engine has to give you the total horsepower of the engine.
Find the length of the sides of the object. Good for finding how much fencing you would need to enclose an area.
The lengths of each of its sides.
If you need to find how big something 2-D is you need to know how to find the area of various shapes. If carpeting you need area. You don't think about it but area is very important. Math isn't useless and is very important int he real world.
You would need to divide it into triangles, find the area of each triangle and sum these areas together.
FIrst we need to know what the object is? Perhaps you mean a cone or a cylinder?
You need the area to find the volume of an object.
Its shape and dimensions
Find the length of the sides of the object. Good for finding how much fencing you would need to enclose an area.
the three dimensions needed to find the area of a rectangular solid object are: Height, Length and Width.
The lengths of each of its sides.

You would need some more information.
If you want to find the surface of something, you must first specify which shape or object you wish to find the surface of, and need to say which area you are looking for, Lateral or Total surface area. Then someone will be able to answer your question.
If the shape is a square, find the square root of the area and that will be the height and the width. Otherwise, you would need to find out more than the area.
