That room would be 169 s.f.

16x16 square feet = 256 square feet, so two tiles will suffice.

9 A square yard is 3 feet across and 3 feet long. 3x3=9
20
16 square feet with less than one square foot of tile remaining
Multiply the two dimensions to get the area. Convert square inches to square feet by dividing by 144 and the calculation will give you 55.16 square feet.
About 1.2 square feet x 63 tiles
169 square feet. Multiply the two dimensions - the result is the number of square feet.
That room would be 169 s.f.
13'x13' = 169 square feet
141
the dimensions of one tile is 13x13 inches or 1.083x1.083 feet. Therefore area of one tile is 1.1736 square feet and that of 196 tiles is 196x1.1736=230.027
You have to multiply the two dimensions to get the area. In this case the answer will be 169 square feet.
The best way to figure out how many 13x13 tile will be needed to cover 30 sf of floor is to calculate 13x13/144 give coverage per tile (1.1736), then take 30/1.736 = 25.56 tiles.
184 would do it but get 185.
