A rectangle floor that measures 3 m by 2 m covered by 384 square tiles. Determine the side length of each tile, in centimetres. State any assumptions you make.
3m = 300cm
2m = 200cm
l x w = A
300 x 200 = 60 000cm2
60 000cm2 / 384 = 156.25cm2
1 tile = 156.25cm2
√156.25cm2 = 12.5cm2
Each side length of the square is 12.5cm2
All 384 square tiles are 12.5cm2
