Perimeter of rectangle Rectangle is a four-sided polygon having two dimensions i.e. length and breadth. Formula of Perimeter: Perimeter of a rectangle = sum of four sides = AB + BC + CD + AD = length + breadth + length + breadth = 2 length + 2 breadth Then, we will get: Perimeter of a rectangle = 2 × (length + breadth) Question for practice : 1. Find perimeter of rectangle whose length is 16 m and breadth 12 m .  Length=16 m Breadth=12 m Perimeter of rectangle= 2( l+b)                                           = 2(16+12)                                            = 2(28) =56m 2. Find perimeter of rectangle whose  A rectangular swimming pool is 9 m long and 4 m broad. Find the area of the swimming pool. Length of the rectangular swimming...

How to find Perimeter of Triangle?  The perimeter of Triangle is sum of all its sides . It means perimeter of Triangle is equal to sum of its sides . let, that a, b and c are sides of Triangle then perimeter of triangle = a+b+c. Let us consider some of the examples on perimeter of a triangle: 1. Find perimeter of triangle having sides of      3cm , 4cm and 5cm.          Perimeter of triangle= 3+4+5=12cm 2. Find perimeter of triangle ABC where              sides are 6cm , 6cm and 5cm.          Perimeter of triangle= AB +BC+CA= 6+6+5                                             = 17cm 3.Find the perimeter of an equilateral triangle whose one side is 6 cm. A triangle in which all the sides are equal is called an equilateral triangle. Perimeter of the equilateral triangle = 3 × si...
