Question

Joe wants to cover the floor of a room 300 cm wide and 400 cm long by square tiles. If each square tile is of side 50 cm then find the number of tiles required to cover the floor of the room.       ​

Answer 1

Answer:

48

Step-by-step explanation:

area of the floor= area of the square tiles × no. of tiles

300×400= 50×50×n

n= 300×400÷50÷50

n= 48

Answer 2

Answer:

48

Step-by-step explanation:

area of floor= 300*400

=120000

area of tile=50*50

= 2500

No. of tiles = 120000/2500

=48
