Change the order of title and featured image in summaries

When I have a page that displays post summaries, the order of items are as follows:

1. Featured Image without link
2. Title
3. Summary

What I want is

1. Title
2. Featured Image with a link to the post
3. Summary

When I look into the code of the theme, I come across a function called the_excerpt(). I can’t find this function in the theme and therefore can’t update it.

So my question is

1. Is there a way to change the order of the title and featured image in this theme?
2. How can I add a link to the post to the featured image, so that when the reader clicks on the picture, they land on the post.
