given height =12 and breath-6m
area- 12*6= 72 metre square
30 cm= 30/100 metre
no. of tiles = 72/0.3*0.3 = 800
if tiles of 15 centimetres should be used then
no. = 72/0.15*0.15= 3200

area of rectangle = l×b
then, 12m × 6m = 72 m square
area of square tile = side square
then, 30cm × 30cm = 900cm square
then, tiles required for flooring = 720000 ÷ 900
800 tiles
then, 12m × 6m = 72 m square
area of square tile = side square
then, 30cm × 30cm = 900cm square
then, tiles required for flooring = 720000 ÷ 900
800 tiles
