so 10x20 is 200 sq. ft? then I do something with 144? I promise I
looked it up, but I couldn't find straight answer. Sorry.

The problem is you're multiplying width by length in your example.
Multiply length by width as in your subject line and you'll be okay.
(Forget 144. That's the running time in minutes of the vid you rented
for tonight.)

Yes, square feet is the length (in feet) x the width (in feet). So, 10'x20'
is, in fact, 200 square feet.
The 144 you mention may have something to do with square "inches". 1 square
foot is 12 inches x 12 inches (144). So, you can multiply square footage by
144 to get the square inches. For your example, 200 square feet = 28800
square inches. I'm not sure why you would need to know that though... :)
To add a little more confusion, "CUBIC" feet is the length (in feet) x the
width (in feet) x the depth (in feet). For instance, if you were pouring a
sidewalk that was 10'x20'x6" thick (6 inches is half a foot, or .5 feet)
you would need 100 cubic feet of concrete.
Of course, concrete is usually ordered in "Cubic Yards" (3'x3'x3' or 27
cubic feet). So, for the 100 cubic feet of the last example, you would need
100/27 or 3.7 cubic yards of concrete.
Class dismissed... :)

Leave it alone if you want your answer in sq. ft.
Multiply by 144 if you want sq. in.
Divide by 9 if you want sq. yd.
Measure in meters if you want sq. m.

Set aside for a moment that you should know this.
Go to google, type "calculating square footage". Press enter.
A bazillion sites give you a "straight answer".
