Write a program that calculates the area and perimeter of a rectangle.

Write a program that calculates the area and perimeter of a rectangle. The area and perimeter are calculated using two separate functions, which both take two arguments of double type for width and length of the rectangle. Calculate the area and perimeter using these two functions in the main program for a rectangle with width and length of 2 cm and 5.5 cm, respectively.

#include<stdio.h>double parameter(double,double);double area(double,double);int main(){double width=2,length=5.5;printf("Parameter is %.2f\n",parameter(width,length));...
