Answer 1

Step-by-step explanation:

The dimension of the floor are 6m×6m or 300cm×300cm

No.of cream tiles is 360 tiles

No. of brown tiles is 240 tiles

Total area of the floor = 600×600

= 3,60,000sq.cm

(each)area of the cream tile = 20×20

=400sq.cm

Total are occupied by 360 tiles =400sq.cm× 360

=144000sq.cm

Remaining area for 240 brown tiles =360000sq.cm-144000sq.cm

=216000sq.cm

Area occupied by each brown tile = 216000/240

= 900sq.cm

Assuming the tile as square, dimensions of the brown tiles are 30cm×30cm
