Answer 1

Answer:

70tiles of 1sq m each

Step-by-step explanation:

• largest possible size means we have to calculate h.c.f then
• h.c.f of 10 and 7= 1
• so length of square tile =1sq m
• area of each sq tile =1m×1m=1sq m
• area of room=70sq m(10×7)
• no.of tile required in that room=70/1=70 tiles
• so tiles of size 1m×1m required totally are 70 tiles....
• that's it..hope this useful ..
