Area and Perimeter of Rectangle using a Class
Calculating the area and perimeter of a rectangle is by defining a class to represent a rectangle and including separate methods for calculating the area and perimeter, namely calculateArea and calculatePerimeter .
Example: Illustration of calculating the area and perimeter of a rectangle in PHP using classes.
PHP
<?php class Rectangle { public $length; public $width; public function __construct($length, $width) { $this->length = $length; $this->width = $width; } // To calculate the area public function calculateArea() { return $this->length * $this->width; } // To calculate the area public function calculatePerimeter() { return 2 * ($this->length + $this->width); } } // Driver code $rectangle = new Rectangle(10, 5); $area = $rectangle->calculateArea(); $perimeter = $rectangle->calculatePerimeter(); echo "Area of the rectangle: $area\n"; echo "Perimeter of the rectangle: $perimeter"; ?> |
Output
Area of the rectangle: 50 Perimeter of the rectangle: 30
Time Complexity: O(1)
Auxiliary Space: O(1)
PHP Program to Find Area and Perimeter of Rectangle
Calculating the area and perimeter of a rectangle is a fundamental geometric operation. The area of a rectangle is given by the formula Area = length * width, and the perimeter is given by Perimeter = 2 * (length + width). In this article, we will explore how to calculate the area and perimeter of a rectangle in PHP using different approaches.
