Area Shortcut
If the area you are measuring has some straight edges, you can use a shortcut when
calculating the size of the area:
1. Trace the curved portion of the area, as previously described, by pressing the stylus
tip down and following the area’s perimeter.
2. When you reach a straight edge, lift the stylus tip at one end of the edge and press it
back down at the other end.
Adding or Subtracting Areas
After calculating the size of an area, you can add an additional area to it, or subtract
another area from it. For example, suppose you are estimating the amount of paving
material that will be needed for a parking lot. You would first measure the size of the
entire lot, and then subtract the sizes of the areas within the lot that will not be paved.
