Question 869230
I assume your room is square measuring 12 feet by 12 feet,
with a surface area of 144 square feet.
What size tiles do you have?
 
If you only have square tiles that measure 1 foot by 1 foot,
each would have an area of 1 square foot, and you would need 144 tiles.
If use tiles of a different size, you may need more or less tiles.
 
If you use square tiles measuring 2 feet by 2 feet (rather large),
each tile will have a surface area of {{{(2feet)*(2feet)=4}}}{{{square}}}{{{feet}}} . Then you will need
{{{144/4=36}}} tiles.
 
If you use square tiles measuring 18 inches (1.5 feet) by 18 inches,
each tile will have a surface area of {{{(1.5feet)*(1.5feet)=2.25}}}{{{square}}}{{{feet}}} . Then you will need
{{{144/2.25=64}}} tiles.
