Question

Square shape tiles of side 40



c.M are to befixed in hall of dimenssion 2.4 dam by 16 m.Find the no of tile

Answer 1

area of hall = area of square * n
here n is number of tiles
2.4*16=0.4*0.4*n(40cm=0.4m)
38.4=0.16*n
n=38.4/0.16
n=48*5
n=240
therefore, total no. of tiles required is 240
