What is perimeter class 6?

 Perimeter: 

Perimeter is the distance around the figure. 
Commonly, Perimeter is the sum of all sides. 

Example 1: If we have a square of side 5 cm. What will be the perimeter of a square? 

Solution: As we know that a square has 4 equal sides and if one side is of 5 cm then all the 4 sides will be of 5 cm. 

Note: For square, Perimeter = 4 x length 
 
Perimeter = sum of all sides      
                 = 5 cm + 5 cm + 5 cm + 5 cm 
                 = 20 cm 

Example 2: If we have a rectangle of length 6 cm and breadth 4 cm. What will be the perimeter of a rectangle? 

Solution: As we know that a rectangle has 4 sides. Two opposite equal and parallel sides. 

Note: For rectangle, Perimeter = 2 (length + breadth) = 2 L + 2 B
                                             
Perimeter = sum of all sides      
                 = 6 cm + 6 cm + 4 cm +  4 cm 
                 = 20 cm
