SAsphere = 4πr2 = 4 x π x 22 = 4 x 4 x π = 16π = ~50.272 square feet.
(33 x 4) = 132 square feet on the floor (33 x 4) = 132 square feet on the ceiling (33 x height) square feet on each of two walls (4 x height) on each of the other two walls Total = [ 264 + (74 x height) ] square feet
70 square feet equals a surface of 2 feet x 35 feet (or 4 feet by 17.5 feet or 8 feet by 8.75 feet)

First you convert the inches to feet by dividing by 12 inches per foot. This gives (24/12) x (16/12) = 2 x 4/3 Then you multiply out 2 x 4/3 = 8/3 = 2 and 2/3 square feet. Or, conversely, multiply 24 x 16 = 384, and divide by 144 (sq. inches in a square foot), with the same answer : 2 and 2/3 or 2.66 square feet.
If that is 2' x 4' it would cover 800 square feet. If it is 2" x 4" it would cover about 5.5 square feet.
2 meters x 2 meters is equal to 4 square meters. To convert to square feet, you would multiply by the conversion factor (1 square meter = 10.76 square feet), so 4 square meters is equal to approximately 43.05 square feet.
It is: 2 feet times 2 feet = 4 square feet
2 x 2 square feet? Do you mean 2 feet x 2 feet? If so, that is 4 square feet and you will need 200 divided by 4 = 50 tiles of 4 sq.ft. That is without wastage or cutting etc.
4 square feet. Multiply length by width - the result is the area in square feet.
8 square feet
8 square feet
2 ft x 4ft = 8ft²
20 feet x 4 feet = 80 square feet.
4' X 6= 24 square feet.
Let the sides of the squares be x and x+2: (x+2)(x+2)-x2 = 44 square feet x2+4x+4-x2 = 44 4x+4 = 44 4x = 44-4 4x = 40 x = 10 Length of the smaller poster = 10 feet Check: 122-102 = 44 square feet
