Perimeter of a Rectangle

Here is the formula to find the Perimeter of a Rectangle...

  

Perimeter of a Rectangle = 2a + 2b

where a and b are the breadth and height respectively...

For example : Suppose the breadth of a rectangle is 5 cm.

and height of a rectangle is 6cm.

so the Perimeter of a Rectangle = 2x5 + 2x6

i.e.,  22cm.

Here is the program to calculate the Perimeter of a Rectangle...

Perimeter of a square

Here is the formula to find the Perimeter of a Square...

Perimeter of a Square = 4 x (Length of a Side)

For example : Suppose the length of a side is 5 cm.

so the perimeter of a square = 4 x 5.

i.e., 20 cm.

Here is the program to calculate the Perimeter of a Square..
