# Program to calculate area and perimeter of a rhombus whose diagonals are given

Given the length of diagonals of a rhombus, d1 and d2. The task is to find the perimeter and the area of that rhombus.

A rhombus is a polygon having 4 equal sides in which both the opposite sides are parallel, and opposite angles are equal.

**Examples:**

Input:d1 = 2 and d2 = 4Output:The area of rhombus with diagonals 2 and 4 is 4. The perimeter of rhombus with diagonals 2 and 4 is 8.Input:d1 = 100 and d2 = 500Output:The area of rhombus with diagonals 100 and 500 is 25000. The perimeter of rhombus with diagonals 100 and 500 is 1019.

Area of the rhombus =

Perimeterof the rhombus =

Below is the implementation of above approach:
