Calculating a scale ratio based on total sqft

Hi,


I have a printout of a total office layout and know the real sqft for three of the offices. I need to figure out the sqft of the rest of the offices using a scale. I can measure the office LxW using mm on a ruler and find the total mm area of the office on paper. I need to use this mm to build a scale ratio for the rest of the offices.


My thinking, say I know an office is 93sqft, it's length = 15mm on paper and width = 7mm on paper.


15mmx7mm = 105mm on paper...105sqmm -> 0.00113021sqft


(0.00113021:93sqft) -> this should be the scale ratio?


So another office is 16mm X 14mm = 224sqmm -> 0.00241112sqft


0.00241112 x 82285.59 = 198 sqft, right?


This seems way too complicated. Is there an easier way?

Thanks for the insight, however, we are unable to take actual measurements of the space and are relying on the layout and figuring out a scale. What we know for sure, actual SQFT, and then it's measuring the office space on with a ruler and trying to figure out a scale for the other unknown SQFT
