C++ Program To Find Area And Perimeter Of Rectangle
A rectangle is a flat figure in a plane. It has four sides and four equal angles of 90 degrees each. In a rectangle all four sides are not of equal length like squares, sides opposite to each other have equal length. Both diagonals of the rectangle have equal lengths.
Examples:
Input: 4 5
Output: Area = 20
Perimeter = 18
Input: 2 3
Output: Area = 6
Perimeter = 10
Formulae :
Area of rectangle: a*b
Perimeter of rectangle: 2*(a + b)
Below is the implementation of the above topic:
C++
#include<iostream>
using namespace std;
int areaRectangle( int a, int b)
{
int area = a * b;
return area;
}
int perimeterRectangle( int a, int b)
{
int perimeter = 2*(a + b);
return perimeter;
}
int main()
{
int a = 5;
int b = 6;
cout << "Area = " <<
areaRectangle(a, b) <<
endl;
cout << "Perimeter = " <<
perimeterRectangle(a, b);
return 0;
}
|
Output:
Area = 30
Perimeter = 22
Time Complexity: O(1)
Space Complexity: O(1) as no extra space has been used.
