840 sqft
If the given dimensions are in feet then 7 times 7 = 49 square feet
7x7= 49 49-9=40 The answer is 40.
2 tiles of 7 ft x 7 ft will be enough.
Multiply the length and width of (for instance) a room, measured in feet, will give the square footage of the room. For example: 15 x 12 = 180 sq ft
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
49
So say you wanted to get the area of a 3d rectangle. you would do lengthxwidthxheight. So you could say you would do 7x7x17. 7x7=49 and then 49x17=833
You want a about 8000btu for a room that size
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
1,500 square feet (30x50 = 1,500)
150 sqft
It's 459 sqft.
20 Sqft.
840 sqft
Assuming measurements are in feet, the area is 208 sqft
12x12= 144 sqft
