find the area of a rhombus in php

To find the area of a rhombus in PHP, you can use the formula:

area = (diagonal1 * diagonal2) / 2

Where diagonal1 and diagonal2 are the lengths of the two diagonals of the rhombus.

Here's the PHP code to implement this formula:

main.php
<?php
$diagonal1 = 10; // length of diagonal1
$diagonal2 = 8; // length of diagonal2

$area = ($diagonal1 * $diagonal2) / 2; // formula to find area

echo "The area of the rhombus is " . $area;
?>

In this example, the length of diagonal1 is 10 and the length of diagonal2 is 8. The formula is then used to calculate the area of the rhombus, which is 40. The result is then printed out using the echo statement.
