Ik wil iets verwijderen in een php bestand

Hi, ik ben niet echt thuis in PHP maar wil dit php bestand wijzigen. Heb al het één en ander geprobeerd maar kreeg alleen maar foutmeldingen.

Het betreft een contact pagina op mijn website (https://psz-johandewitt.nl/index.php/contact1)

Ik wil het formulier gedeelte weg hebben zodat alleen de Map en de adresgegevens overblijven.
Voor jullie waarschijnlijk een makkie:-). Zouden jullie mij hiermee kunnen helpen? alvast bedankt.
Dit is het default.php (contact) bestand:
