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

Given - Tile measure: 25 by 20 cm

Wall size: 4 by 3 metres

Find - Number of tiles required to cover the wall.

Solution - Firstly measuring the area of wall by multiplying length and breadth of wall.

Area of wall = 4*3

Area of wall = 12 metre².

Converting the measure of tile in metres.

So, it will measure = 0.25 by 0.2 metre

Now, area of marble tile = 0.05 metre²

Further, number of tiles required = 12/0.05

Number of tiles required = 240

Hence, to cover the wall 240 tiles are required.
