• 240 tiles

Correct question :

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

Given:

• Dimensions of the marble = 20 cm × 25 cm
• Dimensions of the wall = 4 m × 3 m

To Find:

• Number of tiles required

Solution:

➥ (Converting all the dimensions from cm to m)

➦ Dimensions of the tile = 0.2 m × 0.25

Number of tiles required is given by,

➠Number of tiles = Area of the wall/Area of the tile

➠Number of tiles = 4 × 3/0.25 × 0.2

➠Number of tiles = 12/0.05

➠Number of tiles = 240

Hence 240 tiles are required to cover the wall.
