A polygon’s perimeter is the sum of the lengths of its sides. For instance, if you have a rectangle of length 8 cm and width 5 cm, the perimeter is 2(8 + 5) = 26 cm. For a pentagon with sides 4, 4, 5, 7, and 7, the perimeter is 4 + 4 + 5 + 7 + 7 = 27. Perimeter calculations guide practical decisions like fencing land, framing pictures, or sewing. Learning to quickly sum side lengths fosters efficiency in geometry problems, blueprint analysis, and real-world measurement tasks.
