Question

A marble tile measures 25 cm by 20 cm . How many tiles are required to cover a wall of size 3m 50 cm by 2m

Answer 1

25cm⇒m=0.25m

20cm⇒m=0.2m

3m×0·5m×2m÷0.25m×0.2 m

3÷0.05=60

answer 60 tiles

Answer 2

Answer:

Step-by-step explanation:

using formula ( length into breadth ) Area of rectangle

then

25cm multiply 20cm we get 500cm^2

and

400cmm multiply 300cm we get 120000cm^2

because 1m = 100 cm

then divide 120000cm^2 by 500cm^2

we get 240 tiles
