Are you asking if it is 12 feet x 24 feet, or 12 inches x 24 inches? That makes a difference. 12 feet x 24 feet is 288 square feet, but 12 inches has to be converted to 1 foot and 24 inches has to be converted to 2 feet. Then you have 1 foot x 2 feet, which is 2 square feet.
It is: 24 square feet
= 15 x 24 /(12 x 12) = 2.5 sq feet
Diameter is 24 feet, Radius is 24/2 = 12 feet Area of circle = pi x r x r = 3.1415 x 12 x 12 = 3.1415 x 144 = 452.376 square feet
12 x 24 = 288 sq.ft
To find square footage, multiply length x width: 24 x 12 = 288 sq ft
Assuming 18 inch x 24 inch, result = (18/12) x (24/12) sq feet = 1.5 x 2 = 3 sq feet
12 x 24 = 288 sqft.
The square footage, or area, is 24' x 34' = 816 sq ft. The height has no effect on the area.
24 inches = 2 feet. So 2 feet x 6 feet = 12 square feet.
24 x 24 = 576 square feet.
24 sq feet = 24 x 12 x 12 sq inches number of tiles = 24 x 12 x 12 / (16 x 16) tiles = 13.5 tiles
