How to remove City Area

as I also delete the city area from the profile and from the ad ?

Hello
Very easily, edit item-post.php and user-profile.php.
Should not be complicated at all.

what line should I delete that doesn't work for me

What exactly does not work? Have you tried to search city_area?

that's what I want it to look like
but I can't do it

City area code in user profile:
              <div class="row">
                <label for="cityArea"><?php _e('City Area', 'gamma'); ?></label>
                <div class="input-box"><?php UserForm::city_area_text(osc_user()); ?></div>
              </div>
City area code in item post:
            <div class="row city-area">
              <label for="address"><?php _e('City Area', 'gamma'); ?></label>
              <div class="input-box"><?php ItemForm::city_area_text($prepare); ?></div>
            </div>

thank you very nice
