Perimeter The perimeter meaning can be understood from the fact that ‘ perimeter ’ is a combination of two terms namely; ‘peri’ which implies around, and ‘metron’ which signifies measure. Perimeter is defined as the length of the boundary enclosing a geometrical figure. The perimeter incase of a polygon is the total of all the sides added together. For other figures like circles and ellipse we need to find the length of the boundary of the object. In other words, perimeter is the ...

Perimeter of Different Shapes – Formulas We know every shape is different from one another. Thus, the formula for perimeters of geometric shapes also varies from one shape to another. Some common shapes and formula for finding their perimeters are as follows. Perimeter of Rectangle Rectangle is a four-sided polygon having two dimensions i.e. length and breadth. Perimeter of a rectangle = sum of four sides = AB + BC + CD + AD = length + breadth + length + breadth = 2 length + 2 breadth ...
