Answer:
here is your answer mate
Step-by-step explanation:
ATQ,the area of the floor of floor = area of n number of square tiles.
in this type of questions we should not use surafce area formulas... we should instead find the greatest number which divides the dimensions of the room..that is we should find the HCF of the l and b of the room.
HCF(720,520) = 40cm (find this out by prime factorisation)
therefore,the greatest lenght of the side of the square will be 40 cm.
extra answer:
no.of tiles required =
720×520÷40²
234 tiles.
