Question

A marble tile measures 10 cm × 14 cm. How many tiles will be required to cover a wall of size 2.8 m × 4 m?

Answer 1

Hi friend,
---------------------------------------------------------------------
Length of the tile=10 cm
Breadth of the tile=14 cm
Area of the tile=L*B
=10*14
=140 cm^2

Length of wall=2.8m=280 cm
Breadth of wall=4m=400 cm
Area of the wall=L*B
=280*400
=112,000

Now the number of tiles needed to cover the wall=
AREA OF WALL/AREA OF TILE
=112000/140
=800

800 tiles are needed to cover the wall with tiles.
