Hi there,
Convert your wall measurements into
cm. 2.7m = 270cm, 2.25m = 225cm
3m = 300cm
Area of long wall = 300cm x 270
= 81000cm^2
Area of short wall = 300cm x 225cm
= 67500cm^2
2 Long walls = 162,000cm^2
2 Short walls = 135000Cm^2
...........
162,000 + 135000 =297000cm^2
Area of tile = 15cm x 15 cm = 225cm^2
297000/225 = 1320 tiles
Hope this helps:-)
