Length times width will give you area. So this comes out to 400 square feet.
It is: 20 times 20 = 400 square feet
6,400 square feet (400 x 16 = 6,400).
400 (20x20) square inches is 2.78 square feet.
If that is 20ft by 20ft then there are 400 square feet
400 square meters are 4.3 thousand square feet.
1 foot = 0.3048 meter 400 sq feet = 400 x 0.3048 x 0.3048 sq meters
400 square meters is 4,305.56 square feet.
1 foot = 0.3048 meter 400 sq feet = 400 x 0.3048 x 0.3048 sq meters
The area inside a 400-meter running track is approximately 87,120 square feet. This calculation assumes a standard 400-meter track with lane widths of 1.22 meters each.
In order to determine the number of meters in 400 square meters, we need to take the square root of 400. The square root of 400 is 20. Therefore, there are 20 meters in each dimension of a 400 square meter area.
400x1.6-6,400 sf
Just about 400
400 square feet
I'm going to say 400.
400 square feet (20 x 20 = 400)
400 sq cm equals 0.43 square feet.
