Answer:
400 tiles
Explanation:
Calculate the area of each tile, in m^2:
30 cm = 0.30 m
(0.30 m)^2 = 9.0 x 10^-2 m^2
Divide this into the total area:
(36m^2)/(9.0 x 10^-2 m^2)= 400 tiles
====
Another approach is to note that 6m^2 could be envisioned as a square with sides of 6 m. Calculate the tiles needed to stretch along one side:
6 m = 600 cm
600 cm/30 cm = 20 tiles
It takes 20 tiles to cover one direction
It would also take 20 tiles for the other direction, so a mosaic of 20 by 20 tiles would cover the 36 m^2.
20 x 20 = 400 tiles
