Classroom area, brick side length and the number of blocks required out of proportion______ ．
Because the area of the square brick × the number of blocks required = the area of the classroom (certain), the ratio of the side length of the square brick to the number of blocks required is not certain, and the product is not certain, so the area of the classroom is certain, and the side length of the square brick is not proportional to the number of blocks required, so the answer is: correct
What's the proportion between the side length and the number of tiles when the floor area is fixed?
I know it's inverse proportion, but why? If it's inverse proportion, why isn't the radius and area of the circle inverse proportion?
The landlord said: I know it's inverse proportion
This statement is wrong!
The correct should be: the number of blocks is inversely proportional to the square of the side length of the square brick!
Therefore, another question of the landlord is not a question
