1. a sq is 10 by 10
2. With these dimisions the size will be 54 square feet. You get that by multiplying the width and the length. The coverage for a roof including "over-lap" is 34 square feet. Subtract a foot from both width and length, and this is the coverage area to install a roof.
3. you're question is about as messed up as a soup sandwich... the sheet your are asking about is a rectangle yet you want the area of a square metal roofing cover...
