Creating form with two fields in one row and one field in another row

[Anonymous]

Hello! I'm trying to create a landing page with a form. I would like the form to look like the picture below but I am unable to figure out how to do it.

I can get it to display either in 1 column or 2 column format but I am unsure of how to display it so that it does both (or maybe it's not possible?).

Thanks in advance for any assistance!
