Answer 1

Answer:

960

Step-by-step explanation:

$area \: of \: rectangle \: = \: l \: \times b$

Area of rectangular floor = 800cm x 600cm

= 480000cm²

Area of rectangular tiles = 25cm x 20cm

= 500cm²

Number of tiles required = Area of floor / Area of tiles

= 480000/500

No. of tiles required = 960

Answer 2

Answer:

960 tiles

Step-by-step explanation:

length of floor = 8m

= (8*100) cm = 800cm

breadth of room=6m

=(9*100)cm=600cm

area of floor=l*b

=800*600

=480000cm²

length of tiles = 25cm

breadth of tiles=20cm

area of 1 tile=l*b

=25*20

=500cm²

required no. of tiles = 480000/500

=960 tiles
