Google Form Plugin, textarea too small

I just installed the Google Form Plugin and added it to one of my pages. When viewing the Google Form alone, the “textarea” (paragraph text box) is large and invites bigger responses. When viewing the form on my WordPress page, this box is narrow but tall. How do I make the textarea appear larger (wider)?

I’m new to WordPress and have very little knowledge of coding. Step by step process for fixing this is appreciated.
