Perimeter of a Polygon
🎬 Video Tutorial
(0:01) Perimeter of a Polygon: The total length around a polygon. Add up the lengths of all sides to find the perimeter.(0:12) Perimeter Formulas: For rectangles, use $2 \times (\text{length} + \text{width})$. For squares, the perimeter is $4 \times \text{side length}$.(0:55) Triangle Perimeter: For a general triangle, add all three sides. For isosceles triangles, use $2a + b$; for equilateral triangles, use $3a$.(1:48) Complex Shapes: For L-shaped polygons, rearranging edges into a rectangle can make perimeter calculations easier.
