A good quality 1 bedroom apartment is about 850 square feet. Look at an official Badminton (shuttlecock) court (real court or diagram with dimensions). The overall dimensions are 44 feet length and 20 feet width. That area is 880 square feet, a little (30 square feet) over your number.
3,056.95 sq feet.
500 sq meters = 5,381.96 sq feet (rounded)
861.11 square feet.
1,453.13 square feet.
3,605.91 square feet.
1 sq. yard = 9 sq. feet. 238 sq. yard * 9 sq. feet/1 sq. yard = 2142 sq. feet
850 sq feet = 78.967584 sq meters
54 sq mts is 576.18 sq feet. multiply 54 X 10.76 ( one sq. mt is 10.76 sq feet ) = 576.18 sq. feet
200 (square meters) = 2,152.78 square feet.
4840 sq feet = 450 sq metres.
There are 9 square feet in a square yard. In this case the answer will be 900 square feet.
It is 144 (12*12) sq inches.
