Area of rectangle = Length x Breadth
= 9x 9= 81sq feet
Acc. to me a room has three dimensions length, breadth and height.
If you know the area of the woom and length and breadth you can find height.
108sf
135
8' x 9' = 72 square feet.
It I'd 12 multiplied by 9 aka 108.
216 sq ft
12 x 9 = 108 ft2
9 x 11 = 99
16 by 9 is equal to 16 times 9....which is 144
Assuming the room is 9 ft by 14 ft (the question does not say so), the area would be 9*14 = 126 square feet
Assuming the room is 9 ft by 13 ft (the question does not say so), the area would be 9*13 = 117 square feet
For 9 ft x 20 ft = 180 ft²
Oh, dude, math time! So, to find the square footage of a room, you just multiply the length by the width. In this case, 9 feet times 5 feet gives you a total of 45 square feet in that room. So, like, that's your answer.
