The perimeter of a polygon is the combined length of all its straight-line sides. We can use the properties of simple polygons like triangles or rectangles to find the perimeter of irregular polygons, … [Read more...] about Perimeter of a Polygon
Perimeter of Geometric Shapes
The perimeter of geometric shapes is the length of the line defining the shape, or the distance around the shape.
For polygons, it is the sum of the lengths of all the straight lines that make up the polygon.
For circles, the perimeter is called the circumference, and it is given by the formula C=2*r*π , where r is the circle's radius, and π is a special mathematical constant, which is not a rational number, roughly equal to 3.14159.
