20ft² = 1.858m²
18ft is equal to 6 yards so a square of 6yds x 6yds would have an area of 36 square yards.
30.096196 square meters
12 ft x 20 ft = 240 sq. ft.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.
To convert square feet to square meters, you would multiply by 0.0929. Therefore, for a 20ft x 20ft area, you would calculate 20ft x 20ft = 400 square feet. To convert this to square meters, you would multiply 400 by 0.0929, resulting in an area of approximately 37.16 square meters.
360ft² = 33.45m²
If that is 20ft by 20ft then there are 400 square feet
216 square feet.
18ft² = 1.672m²
Multiply width by length to get the area. The answer would be 342.2 square feet.
400 square feet
140
20 feet x 10 feet = 200 square feet
There are: 20 times 9 = 180 square feet
20ft² = 1.858m²
120 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
