PHP class for rectangle: Area and perimeter calculation

Last update on December 20 2024 10:21:24 (UTC/GMT +8 hours)

Write a PHP class 'Rectangle' that has properties for length and width. Implement methods to calculate the rectangle's area and perimeter.

Sample Solution:

PHP Code :

<?php
class Rectangle {
    private $length;
    private $width;

    public function __construct($length, $width) {
        $this->length = $length;
        $this->width = $width;
    }

    public function getArea() {
        return $this->length * $this->width;
    }

    public function getPerimeter() {
        return 2 * ($this->length + $this->width);
    }
}

$rectangle = new Rectangle(12, 9);
echo "Area: " . $rectangle->getArea() . "</br>";
echo "Perimeter: " . $rectangle->getPerimeter() . "</br>";
?>

Sample Output:

Area: 108
Perimeter: 42

Explanation:

In the above exercise -

The "Rectangle" class has two private properties: $length and $width, which represent the rectangle's dimensions.
The constructor method __construct() initializes the rectangle's length and width.
The getArea() method calculates and returns the rectangle's area by multiplying its length and width.
The getPerimeter() method calculates and returns the rectangle perimeter using the formula: 2 * (length + width).
