The area of the floor =6*6
=36m^2
The area covered by cream colour tiles = 360*0.2*0.2
= 14.40m^2
Measurement of side of brown colour tile = a
The area covered by brown colour tiles = 240*a^2
36-14.40m^2. = 240*a^2
21.6/240. = a^2
0.09. = a^2
0.3m = a
The dimension of brown colour tile = 0.3m*0.3m. (Or). 30cm*30cm
