Assuming 206 and 200 are feet.
206 × 200 = 41,200 square feet.
79.7778 square yards (0.111111 square yards per square foot).
That is 432 sq inches
7,405 square feet is about 0.17 acre.
1 decimeter is a unit of length and sqft is a unit of area, you can not equate the two, so your question is meaningless.
A yard is a unit of distance. A square foot is a unit of area. The two units are therefore incompatible.
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
20 Sqft.
It depends on how many square feet the box will cover. I found two different brands: one covered 22.93 sqft, the other 17.59 sqft. your room is 12' x 14' = 168 sq.ft so 168 sqft / (22.93 sqft / box) = 7.32 boxes for my first example and 168 sqft / (17.59 sqft / box) = 9.55 boxes for my 2nd example Hope this helps
12x12= 144 sqft
You want a about 8000btu for a room that size
7 x 7 = 49
269.23
1418 sqft = 131.74m2

2,800 sqft is 0.064 acre.
1,500 square feet (30x50 = 1,500)
4ft * 8ft = 32 sqft = 2.9729 sq metres (to 4 dp)
