how do you go from square feet to feet
1 acre = 43,560 square feet. To calculate the area of a room in square feet, measure the length and width of the room in feet, then multiply these figures together to give an area in ftÂ². For example, a room measuring 12 ft x 15 ft would be described as having an area of 180 ftÂ² (12 x 15 = 180).
