Answer: If Jenny has 50 tiles and she puts them in order, one next each other, and creating four rows of the same lenght (the same number of tiles), to, in this way form a rectangular area, we can calculate how many tiles are in each row by dividing 50 0 by 4 (50 tiles in 4 rows), the result is 12 (12 tiles in each row) and the remainder is equal to 2, which is the number of tiles that will be left over.
