Jackson uses a table saw to cut a piece of plywood from one corner to the opposite corner. If the piece of plywood measured 16 inches by 12 inches, how long was the cut that Jackson made?
You're trying to find the hypotenuse. To do that you have to square 16 and 12. That gets you 256 and 144. You then have to add the 2 numbers. That gets you 400. Finally square root 400 to get 20.
