Question

A marble measures 10cm by 12cm. How much tiles will be required to cover a wall of size 6m by 4m

Answer 1

Answer:

5

Step-by-step explanation:

length of a marble = 12 cm

breadth of a marble = 10 cm

Area of a marble = length × breadth

=> 12 cm × 10 cm

=> 120 cm²

Now, Length of the wall = 6 m

breadth of the wall = 4 m

Area of the wall = length × breadth

=> 6 cm × 4 cm

=> 24 cm²

Number of tiles required = Area of the wall / Area of the tiles

=> 120 cm² / 24 cm²

=> 5
