1 square yard is equal to approximately 0.8361 square meters.
1 foot = 0.3048 meters 1 sq foot = 0.3048 x 0.3048 sq meters = 0.0929 sq meters Answer = 25 x 13 x 0.0929 sq meters = 30.1925 sq meters
43560 sq feet = 43560 x 0.3048 x 0.3048 sq meters = 4046.8564 sq meters
1 foot = 0.3048 meters Answer = 118.75 x 0.3048 x 0.3048 sq meters = 11.03224 sq meters
1 foot = 0.3048 meters 1 sq foot = 0.3048 x 0.3048 sq meters = 0.0929 sq meters Answer = 174/0.0929 sq feet = 1872.9817 sq feet
48750 sq m
3.5m x 5.5m = 19.25 m2
6743 sq ft ≈ 626.45 sq m 1 ft = 0.3048 m (exactly) 1 sq ft = 1 ft x 1 ft = 0.3048 m x 0.3048 m ≈ 0.0929 sq m ⇒ 6743 sq ft ≈ 6743 x 0.0929 sq m ≈ 626.445 sq m
9 square meters
0.3048 m = 1 ft (exactly) ⇒ 33 sq m = 33 x 1 sq m = 33 x (1 m x 1 m) = 33 x ((1 ÷ 0.3048) ft x (1 ÷ 0.3048) ft) ≈ 355.21 sq ft
100m x 100m = 10000 sq m 1 acre = 4046.85642 sq m 10000 / 4046.8562 ~= 2.47 acres.
2.60 m x 3.00 m = 7.80 sq meters
1 km = 1,000 m 1 sq km = 1 km x 1 km = 1,000 m x 1,000 m = 1,000,000 sq m ⇒ 1.89 sq km = 1.89 x 1,000,000 sq m = 1,890,000 sq m
54 sq metres * 50 mm = 54 sq m * 0.05 m = 2.7 metres3
7 m x 11 m = 77 sq meter
Assuming you meant "square feet is 9.9 sq meters" as feet are measure of length whereas sq meters are a measure of area:1 ft = 0.3048 m (exactly)1 sq ft = 1 ft x 1 ft= 0.3048 m x 0.3048m= 0.09290304 sq m→ 9.9 sq m = 9.9 ÷ 0.09290304 sq ft≈ 106.56 sq ft
1,800 mm x 310 mm = 0.558 sq meters.
