Question

a room is 49/4 long and 7 m wide. The maximum length of a square tile to fill the floor of the room with whole numbers of tiles should be

Answer 1

49/4=12.25m long
& 7m wide so.....
area of room is 12.25*7=85.75m²
now we use square tiles....
so area of square tiles =85.75m²=b*b
therefore b=3.04m
so no. tiles can be used=85.75/3.04 =28.20=28approx tiles can be used

Answer 2

Answer:

L=49/4 m

=1225cm

w= 7cm=700cm

maximum length of square tiles= HCF of 1225,700)=175cm
