How to resize Widget Area One Position 3

Let me make sure I understand what you are trying to do. You placed an image in the sidebar, but the image is showing up smaller than expected? How did you add the image, using a Text widget? Can you please post a link to your site so I can see what is happening?

OK, I found your site from another post. Please remember to include a link to your site every time you create a post so I don’t have to hunt around for it. Thank you.

In position 3 of the side bar, I see an Ad Rotate widget, and it is showing this GIF image from Photo Travel & Tours. Are you trying to make the image show up bigger?

Add this rule to the end of your various.css file:

.widget_adrotate_widgets img {
    max-width: none;
}

One problem with the image, though, is that it is actually wider than it looks. It is blue on the left side and white on the right, so that is why the image didn’t look like it was filling up the entire sidebar. You are going to have problems on mobile widths because the white part is going to extend the width of the page to the right. You should edit the image and crop it down to just the blue part.
