Perimeter of square

 PERIMETER OF SQUARE 

The perimeter of square is calculated by adding its four sides. We know that all the sides of a square are equal and hence, its perimeter will be 4 times its side, i.e. 4 × Side.

The formula for Perimeter of a Square

Perimeter of Square (P) = 4 × Side

Where side is length of 

the side of square. 




Example:

1. Find the perimeter of a square whose side      is 4cm.

Sol:  side =4cm

       Perimeter of square= 4×4= 16cm

2.Find the perimeter of a square whose side     is 5 cm.

Sol:   side= 5cm

         Perimeter of square= 4×5 =20cm

3.Calculate the perimeter of a square               having a side of 15 cm.

Sol: side =15cm

       Perimeter of square= 4×15= 60cm

4. If the perimeter of a square is 64 cm,            find its side.

Sol: perimeter of square=64cm

       Perimeter of square= 4×side

     Side = 1/4× Perimeter of square

     Side = 1/4×64

     Side =16cm


More questions for practice

1. If the perimeter of the given square is 12 cm. What will be the length of its side?

Ans:3cm 

2. If side of a square is 8cm. What will be its perimeter?

Ans:32cm

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.

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...
