18ft*20ft = 360 square feet
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.
360ft² = 33.45m²
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.
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.
