Are the floor tiles above drawn to scale?
It does not make a difference what size the tiles are. The important thing is that they are SQUARE tiles.
uhh..for Part II, do we have to find a rule or something to figure out how much tiles the string passes over? or do we just use graph paper and draw the string over a certain amount of tiles?
yes you are finding a rule that would work with any number tiles. If I ask for a 14 by 35 sized floor, you should be able to tell me the answer using the rule without having to draw out all the tiles. Hope that this clears it up.
how are you supposed to measure each tile?
you're not supposed to measure the tiles. The size of the tiles do not matter. They are asking about how many tiles the string touches when stretched corner to corner.
