Question

A marble tile measures 25 cm by 20 cm. How many tiles will be required to cover a wall of size 4 m by 3 m ?

Answer 1

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

Answer 2

Area of marble tile=500cm² How many tiles are required to area of 120000cm²(1m=100cm) 500×p=120000 p=120000/500=24 24 tiles are required to cover a wall of 4m by 3m
