As long as the existing flooring is in good shape meaning not cracking or peeling then that's the best, easiest and most cost effective installation.
gotta know more whats the type of sub floor Is it Lino or Vinyl flooring Is it glued or floating floor?? How old How big & what shape is the bump, is it the only one any discoloration.
Yes and no. If the old linleum is peeling and seems loose then I would pull it up. If however the old linoleum is still in good shape and isn't peeling then yes, but steps must be taken. if it's on a cement floor then you need to coat the floor with a bonding agent or use a higher performing modified thinset. If the linoleum is on a wood subfloor I'd just staple metal lath right over the linoleum and tile it. I would use a bonding agent that most specialized tile stores sell. since there are so many just go to a tile store near you and ask them what they have.

It doesn't! It takes the shape of whatever container you put it in. At least, it takes the shape of the floor of the container.
Lino printing is when you paint a side of an object and put it on a piece of paper or card, and it the shape of whatever part of the object you painted will transfer onto the paper. lino is short for linoleum block printing where you use a linoleum tile as the printing plate. Carve what you want on the plate in reverse and print it.
How about a square floor tile

It is object (lines and curves) or shape you can drawn or use existing pre-defined vector shapes from Custom Shapes in Toolbox.
Gases will take on the shape of the container it is in. Carbon dioxide, for example, will take on the shape of the container, but if emptied from the container, the carbon dioxide, being heavier than air, will sink to the floor and then spread out across the floor.
They change its size and shape.
There is no limit to the number of sides that a shape can have. It is not possible to tell what the largest number is unless you know all the shapes that exist in the universe.
