Question

Sabina wants to cover the floor of her room whose length is 4 m and breadth is Im by square tiles. If each square tile is of side 20cm, then find the number of tiles required to cover the floor of her room.

Answer 1

Answer:

100 tiles

Step-by-step explanation:

1 m =100 cm

length is 4 m=400cm

and breadth is Im=100cm

area of floor= length × breadth

400×100=40000sq cm

each square tile is of side 20cm

area of square tile= side×side

= 20×20=400 sq cm

number of tiles required to cover the floor of her room.

= floor area ÷ tile area

40000÷400

= 100 tiles

number of tiles required to cover the floor of her room= 100 tiles
