If each side of the square is 20-ft, then the area of the square is (20 x 20) = 400 square feet.
20ft * 15ft = 300 square feet.
Area of a circle in square feet = pi*radius2
20ft X 6.25ft = 62.5 ft2
assuming that you've measured the room in feet, then square area=Width x Length... so 12ft x 20ft = 240ft2
400 square feet
If that is 20ft by 20ft then there are 400 square feet
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.
18ft*20ft = 360 square feet
If the 18 stands for the radius, then the area formula : A= Pi r2 can be used. The question is standed strangely.
Not sure which dimension is which. Normally, the square footage of a room is calculated from its length and width, and not height. However, this question gives depth! Is it a dungeon? Anyway, assuming that the depth is the height, the square footage is 20*15 = 300 sq ft
You don't. Its cubinc footage, not square footage.
The square footage of my house is 2,000 square feet.
