You multiply the length by the width, i.e. 47ft x 30ft = 1,410 square feet.
5ft x 4 = 20ft
2000 (square feet) = 185.80608 square meters
200 linear feet equals how many square meters
1 m² ≈ 10.7639104167097 ft²
All you need to do is multiply the length by the width, and it doesn't matter in what order you do it. 20ft X30ft= 600 square feet.
You have to multiply the two dimensions to get the area. In this case the answer will be 600 square feet.
400 square feet
30ft*20ft = 600 sq ft
18ft*20ft = 360 square feet
If that is 20ft by 20ft then there are 400 square feet
A 30ft x 14ft room = 420 square feet.
assuming you mean 20ft by 30ft, you just find the area. To find the area, simply multiply both sides, so 20x30 = 600 sq ft
You multiply the length by the width, i.e. 47ft x 30ft = 1,410 square feet.
20ft * 15ft = 300 square feet.
30*2 = 60 square feet
If you are truly looking for SQUARE FEET for a building with these measurements, more informaiton will be needed. A building, whether square or rectangular, will have only two different measurements. My guess is that you are looking for cubic feet, which would include the height of the building. For Example: 30ft x 20ft x 50ft would be 30 ft wide, 20 foot deep (long), and 50 ft tall. Regardless of the placement and the symbolism of the measurements, the result is the same: 30 x 20 x 50 = 30,000 cubic ft.
