please solve the problem ​

Answer 1

Answer:

Length of the room = 4 m = 400 cm

Breadth of the room = 3 m = 300 cm

Area of the floor of the room = Length × Breadth

= 400 × 300 sq cm = 120000 sq cm

Side of the square tile = 20 cm

Area of the square tile = Side × Side = 20 × 20 sq cm

= 400 sq cm

So, number of tiles required = Area of the floor/Area of one tile = 120000/400 = 300
