About perimeter
Perimeter is the total distance around a shape. For polygons add all sides; for circles use 2πr. Waste factor adds extra length for overlaps, cuts, or mistakes.
Step 2: Material & Labor Cost
Waste & complexity
Waste factor adds extra length. Complexity affects labor: simple = 1.0, moderate = 1.3, complex = 1.7 multiplier.
