Measure the length of the room in feet and the width of the room in feet and multiply the two measurements together. The answer you get is the area in square feet of your room.
Multiply width by length and multiply by 9
Multiply the length of the room times the width.
64 Sq Ft. 8ft x 8ft is 64.
1 sq yd = 1 yd * 1 yd = 3 ft * 3 ft = 9 sq ft. 11 ft * 9 ft = 11*9 sq ft = 99 sq ft = 99/9 sq yd = 11 sq yd
900 square foot
If you mean 20 in x 20 in tiles, the 240 sq ft room is 240 x 144 sq in = 34560 sq in. each tile is 20 x20 = 400 sq in tiles needed are 34560/400 = 86.4 tiles, say 90 tiles
1 sq yd is equal to 9 sq ft, so a room that is 16 ft x 22 ft is 352 sq ft, or divided by 9 is equal to 39.11 sq yds.
The sq ft of a room 6 ft x 9 ft is 54 ft2.
Multiply the length of the room times the width.
264 sq ft.
16 x 28 sq ft...
11 ft * 13 ft = 143 sq. ft, so the room has an area of 143 sq. ft
96 sq ft.
12' * 21 ft = 12*21 sq ft = 252 sq ft.
1440 sq ft
40 x 40 = 1600 sq ft
It is approx. 460 sq ft.
