first of all we will determine the are of room which a square
a = 2.75m
a^ 2 = 2.75 × 2.75 m2
a^2 = 7.56 m2
now the area of a tile = 121× 10^-4 m2
the number of tiles = area of room / area of one tile
= 7.56/ 121 × 10^-4
= 624.79
= 625 ( approximately)
a = 2.75m
a^ 2 = 2.75 × 2.75 m2
a^2 = 7.56 m2
now the area of a tile = 121× 10^-4 m2
the number of tiles = area of room / area of one tile
= 7.56/ 121 × 10^-4
= 624.79
= 625 ( approximately)
