425 sq ft
Assuming that the 12x12 is inches.12 in. x 12 in. = 1 ft x 1 ft = 1 square (sq) footGiven that you have 200 square feet to cover:(200 sq ft) / (1 sq ft) = 200 unitsThat means it takes 200 12x12 in. squares to cover a 200 sq ft. space.If you meant 12x12 to be in feet:12 ft x 12 ft = 144 sq ft.200 / 144 ~= 1.39 units (It would take 1.39 squares to cover it)
180 sq ft if 12 X 15 is actually 12 ft X 15 ft. Otherwise anything you like.
12 ft * 12 ft = 4 yd * 4 yd = 16 sq yards
0.3048 m = 1 ft (exactly) ⇒ 0.3048 m x 0.3048 m = 1 ft x 1 ft ⇒ 0.0929 sq m ≈ 1 sq ft ⇒ 30 sq m ≈ 30 ÷ 0.0929 sq ft ≈ 322.92 sq ft
12 ft x 41 ft = 492 sq ft
One sq yd is 9 sq ft, (3ft x 3ft) so 12 sq yds is 108 sq ft (12 x 9 sq ft)
12' * 21 ft = 12*21 sq ft = 252 sq ft.
18 ft x 12 ft = 216 sq feet or 20.0671 sq meters.
1728 sq. in. 1 foot = 12 inches 1 sq. ft. = 12 in. x 12 in = 144 sq. in. 144 sq. in./ sq. ft. x 12 sq. ft. = 1728 sq.in.
12 in = 1 ft → 1 in = 1/12 ft 1 sq in = 1 in x 1 in = 1/12 ft x 1/12 ft = 1/144 sq ft → 1644 sq in = 1644 x 1/144 sq ft = 115/12 sq ft ≈ 11.42 sq ft
1 sq yard = 9 sq ft. 12 ft x 20 ft = 240 sq ft. 240 sq ft = 26 2/3 sq yards.
144 sq ft
12 in = 1 ft ⇒ 26 in x 38 in = (26 ÷ 12) ft x (38 ÷ 12) ft = 631/36 sq ft ≈ 6.86 sq ft
1 ft = 12 inches 1 sq ft = 12 x 12 = 144 sq in 10 sq ft = 10 x 144 = 1440 sq in
4' x 12' = 48 sq ft
12 FEET * 13 ft = 156 sq ft = 14.49 sq metres
