400 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

There are: 30 times 90 = 2700 square feet

30ft * * * * * No, it is 30 SQUARE feet. Area cannot be measured in feet!

20 feet x 10 feet = 200 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.
