Question

8000 tiles of size 15cm by 15cm are required to cover the entire floor of a hall length 15m what is the breadth of the hall in m​

Answer 1

The area of one tile = Side×Side = 15×15 = 225cm²

The area of 8000 tiles = 8000×225 = 1,800,000cm²

Area of tiles change from cm² to m² = 1800000/10000 = 180m²

When we change cm² to m² then divide by 1000

That 180m² is area of hall because the tiles are fit in the hall so we are taking solution of 8000 tiles.

So, The area of hall = length×breadth = 180m²

let we take breadth = x

15m×x = 180m²

15x = 180m²

x = 180/15 = 12m

The breadth of the is 12m
