To determine what the area of something is, you determine length X width. So to determine how many feet are in 400 sq ft, you must determine what X what equals 400. This would mean that the length is 20 feet and the width is 20 feet.
120,000 sq ft
400 20 x 20 is 400 sq. Ft.
1 ACRE IS 43,560 SQ FT. SO YOUR 200 FT X 400 FT (80,000 SQ FT) IS 1.83655 ACRES, MORE OR LESS. -eXpReXo
1 sq m = 10.76 sq ft, so 400/10.76 = 37.17 sq m
12 ft * 28 ft = 12*28 sq ft = 336 sq ft
400 (sq feet) = 37.161216 sq meters
120,000 sq ft
1 sq. m = 10.7639 sq. ft.so: 400 sq. m. = (400 * 10.7639) 4305.56 sq. ft.
400 ft x 300 ft = 120,000 sq ft = 2.755 acres (approx)
400 ft x 800 ft = 320,000 sq ft. 1 acre = 43,560 sq. ft, so divide 320,000 / 43560 = 7.346 acres.
15 lb. has 400 sq. ft. 30 lb. has 200 sq. ft.
20 ft x 20 ft = 400 sq. ft.
It is not entirely clear what the question is asking but the areas can be configured as80000 sq ft = 400 * 200 sq ft leaving an area of 400 * 200 sq ft, then 40000 sq ft = 400 * 100 sq ft leaving an area of 400 * 100 sq ft, then 10000 sq ft = 100 * 100 sq ft leaving an area of 300 * 100 sq ft, then 5000 sq ft = 100 * 50 sq ft leaving an area of 250 * 100 sq ft.
400 square ft = 37.16 square m
400 20 x 20 is 400 sq. Ft.
15 lb. 400 sq. ft. 30 lb. 200 sq. ft.
1 ACRE IS 43,560 SQ FT. SO YOUR 200 FT X 400 FT (80,000 SQ FT) IS 1.83655 ACRES, MORE OR LESS. -eXpReXo
