<?php
class Segitiga{
    public $alas;
    public $tinggi;

    public function __construct($alas=0, $tinggi=0){
        $this->alas = $alas;
        $this->tinggi = $tinggi;
    }

    public function hitungLuas(){
        return $this->alas * $this->tinggi / 2;
    }
    
    public function hitungKeliling(){
        return $this->alas + $this->tinggi + 
        (sqrt(($this->alas * $this->alas) + ($this->tinggi * $this->tinggi)));
    }
}

$persegi = new Segitiga(3, 4);

echo "alas = " . $persegi->alas . "<br />";
echo "tinggi = " . $persegi->tinggi . "<br />";
echo "luas = " . $persegi->hitungLuas() . "<br />";
echo "keliling = " . $persegi->hitungKeliling() . "<br />";
