Answer 1

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
