25 square feet
To find the area (square feet) of a room, multiply the length by the width. 10 feet x 20 feet = 200 square feet.
I would assume it to be 42 ft depending if you are talking about the inside of the room or the outside perimeter
5.5 feet.
10 ft * 11 ft = 10*11 = 110 square feet.
The area of a room 11 ft x 11.5 ft = 126.5 square feet.The volume of a room 11 ft x 11.5 feet x 7.5 ft = 948.75 cubic feet.
1475 sqare metres = 15,876.8 sqare feet
400 square feet
try multiplying 11 by 15 ....
11 ft * 11 ft = 121 ft2 ======
110
a=b*l 9*11=A A=99 sq feet
7 ft 6 in x 11 ft 6 in = 7.5 ft x 11.5 ft = 86.25 sq feet.
11 ft * 13 ft = 143 sq. ft, so the room has an area of 143 sq. ft
45 sqare feet
