It is either 12 wide and 13 long or 13 wide and 12 long.
12 x 2 + 10 x 2= 44
3 yards x 2 yards
If the room is 9 yards wide by 12 yards long, then 108 square yards.
The ceiling and floor are each (12 x 10) = 120 square feet. In order to calculate the area of the walls, we'd also have to know the height of the ceiling.
10 x 12 = 120 square feet on the floor 10 x 12 = 120 square feet on the ceiling (10 x height) on each of two of the walls (12 x height) on each of the other two walls Total square feet in the room = [ 240 + (44 x height) ] square feet
10 x 12 = 120 square feet.
to get the square footage just multiple length times width. So 10 x 12 = 120 square feet.
About 2.2 grams of dust in the average 10 x 12 room
12 x 12 = 144 144 square feet
120 square feet.
You can't. The length and width don't tell you the height.I might have a 10 x 12 room that's 7-ft high, and youmight havea 10 x 12 room that's 10-ft high.
