Answer 2

☆ Solution ☆

Given :-

• A marble tile measures 30 cm × 25 cm.

To Find :-

• The number of such tiles required to cover a wall of size 4m × 3m.

Step-by-Step-Explaination :-

Length of the wall = 4 m = 400 cm

Breadth of the wall = 3 m = 300 cm

As we know that :-

Area of rectangle = l × b

Putting the respective value,

Area of rectangle = 400 × 300

Area of rectangle = 120,000 cm²

Now,

Area of tiles = 30 × 25 = 750

So,

Number of tiles required = area of wall/ area of tiles

Putting the respective value,

Number of tiles required = 120,000/750

Number of tiles required = 160 tiles

Hence Solved !
