T2125 Home Expenses calculation

Hey Guys, 

I work from my home for my small business and use my workspace for personal use as well, and am trying to determine what to put in the fields for:

-Area, (m²or ft²) or number of rooms, of the workspace

-Total area or rooms in the home (use the same unit of measurement as above)

The calculation instructions in Turbotax are really tripping me up and am hoping someone can help. 

 

Here are my inputs:

Total house area= 100 ft sq (for simplicity's sake)

Area used for work= 20 ft sq (for simplicity's sake)

% of week (7 days) working= 32%

 

Given this, what should I put in these fields?
