I’ve lost my iPad in front of my house.

Start here:

Locate a device in Find My on iPad - Apple Support

Here is Apple’s advice for lost or stolen devices:

If your iPhone, iPad or iPod touch is lost or stolen – Apple Support

Use the Find My app to locate a lost or stolen device – Apple Support

If the Find My iPad feature was enabled prior to it being “misplaced”, then if active, you would stand a good chance of locating it. 

However, if the feature was not activated prior to being misplaced - or the iPad has been inactive or without an active network connection for more than 24 hours, the last known location will not be available - and the opportunity to use technical means to remotely manage or recover the iPad may have been lost.

No.

Beyond facilities offer by Find My, entirely reliant upon the owner having enabled this feature, Apple cannot provide assistance in tracing a lost device.
