answer the following question in the picture
Answers
Step-by-step explanation:
Area of the each square tiles = side² sq.unit
= 15² cm²
= 225 cm²
Area of the Square floor = side² sq.unit
= 3² m²
= 9 m²
9 m² = 9*10000 cm² = 90000 cm²
[1 m² = 10000 cm²]
Therefore, Required number of tiles = Area of the square floor/Area of each tiles
= 90000/225
= 400 tiles.
So, 400 tiles are required to cover the square floor of the bathroom.

solution
here,
length of square tile = 15 cm
and,
lenth of square floor = 3m
therefore,3m = 300cm
to find:no.of tiles = ?
now,
area of square 1 tile = (/)*2
= (15)*2
= 225sq.cm
and,
area of square floor = (l)*2
= (300)*2
=90000sq.cm
now,
since,
no.of tiles = area of square floor
area of square tile
= 90000
225
=400tiles
therefore 400 are no.of tiles which required to covered square floor
