assuming those numbers are in feet: 10 ft * 20 ft = 200 sq. ft.
240 sq feet.
168 square feet.
12 ft * 13 ft = 156 sq feet = 14.49 sq metres.
15 feet by 10 feet is 150 square feet.
3x3 = 9 square feet.
240 sq feet.
129 sq. feet = 14.33 sq. yards
144 sq feet
The answer depends on the units used for 10x20. It should be blindingly obvious to anybody that the answer for 10 ft x 20 ft will be quite different to that for 10 yards x 20 yards.
600ft2
Assuming the room is 18 FEET by 14 FEET, the answer is 252 sq ft
320 sq feet.
351 sq feet or 39 sq yds
144 square feet = 16 square yards.
the formula is LXW=sq feet & then sq feet divided by 9= sq yards 12X25=300 sq feet 300 sq feet divided by 9 sq feet per sq yard-33.33 sq yards to do a 12X25 room
There are 220 sq feet on the floor, and another 220 sq feet on the ceiling. There are also a lot more sq feet on the walls, but we can't total them up without knowing the height of the room.
Assuming its 30 feet then its 30 x30 = 900 sq feet
