Answer 1

Answer:

2000

Step-by-step explanation:

as this a simple question i would give you a shortcut trick

No. of tiles = area of floor / area of each tile

No. of tiles = 40*20 / 0.8*0.5

[ {since 1cm =100m then (80cm =80/100m =0.8m) and(50cm =50/100m =0.5m) } ]

No. of tiles = 40*20*100*100 / 80*50

No. of tiles = 2000
