PERIMETER OF PLANE SHAPES  Definitionn of perimeter   Perimeter is the sum of the length of all the edges of a plane shape. The perimeter of regular and irregular shapes can be found by adding up all the length of the sides present in the given shape.  Perimeter of irregular shapes The perimeter of irregular shape can be found by adding up all the length of the sides of the irregular shape. For example, Consider the irregular shapes shown below, the perimeter of The shape is the sum of all the lengths of of each of the sides of the shape. That is,the perimeter of the irregular shape = b + d + a + c.  Examplee 1: Calculate the perimeter of the irregular shape shown below: Solution 1:  The perimeter of the irregular shape = Sum of all the length of each side of the shape. Perimeter of the irregular shape = AB + BC + CD + DE Perimeter of irregular shape = (2.8 + 2 + 2.5 + 1.8 + 2.5) cm = 11 cm Note: There is no fixed formula for solving the perimeter of irregul...
