if each tile has a perimeter of 1 meter, then 16 tiles will have an area of one square meter

a 3x3 floor has an area of 9 meters.


144.


And boo to the metric system.

a square tile with a perimeter of 1 has a side of .25, and an area of .0625.

An even easier solution is to take the 3x3 dimensions of the floor, determine that the area is 9, and divide this number by .0625.


# of tiles needed= Area(floor)/area(tile)

cover the floor => talking about area here


area of the floor = 9 sq.m.

number of tiles req. = n * s^2 = 9


we know perimeter of tiles is 1 , therefore side is 0.25

n * 0.25 ^2 = 9

n =144
