The average square footage of each retail store is 150000. For short determine the length and width of the area you are working with measured in feet. The formula for the area of a rectangular room is width x length as shown in the figure below.
The conversion 1 square meter 1076 square feet means that 1076 of your paper square feet would fit over one paper square meter.
If you measured in feet inches divide inches by 12 and add that to your feet measure to get total feet. 20ft 20ft 400 sq ft. For example if you have a two-story home thats 2600 square feet one floor would be 1300 square feet Multiply this number by your most recent result to get the estimated square footage of your roof. This yields a product called the area which is expressed in square feet or square inches if you are calculating a much smaller space such as a dollhouse.
