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.
30ft*20ft = 600 sq ft
18ft*20ft = 360 square feet
20ft * 15ft = 300 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.
30*2 = 60 square feet
You have to multiply the two dimensions to get the area. In this case the answer will be 600 square feet.
Ah, what a lovely question! To find the area of a 20ft by 20ft square, we simply multiply the length by the width. So, 20ft x 20ft equals 400 square feet. To convert this to square meters, we need to remember that 1 square meter is approximately 10.76 square feet. Therefore, the area of a 20ft by 20ft square is about 37.16 square meters. Isn't that just delightful?
400 square feet
30 ft * 20 ft = 30*20 sq ft = 600 sq ft
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.
To convert square feet to square meters, you need to multiply by 0.0929. So, for a 70ft x 30ft area, you would calculate 70 x 30 = 2100 square feet. To convert this to square meters, you would then multiply 2100 by 0.0929 to get approximately 195.09 square meters.
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.
