126 square feet. Just multiply length by width - the answer is the square footage.
54 sq ft
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
To get the area you multiply the length and the width. Doing the math gives an answer of 76.5 square feet.
To find the square footage of a rectangular area, you simply multiply the length by the width. In this case, the length is 16 feet and the width is 9 feet. Multiplying 16 by 9 gives you a total of 144 square feet. So, the square footage of a 9x16 area is 144 square feet.
The "square footage" is usually called the "area". A room that measures 3-ft long and 3-ft wide has -- 9 square feet on the floor -- 9 more square feet on the ceiling -- more square feet on the walls, but in order to count those, you have to know the height of the ceiling above the floor.
