Working out square footage
The area of a rectangular space is simply its length times its width. If you measured in feet, the answer is in square feet; in metres, it's in square metres. To convert, one square metre equals about 10.76 square feet. For rooms that aren't rectangular, split the space into rectangles, work out each area, and add them together.
