Google search results showing up full width, no sidebar

I need some help in the formatting of this plugin.

I am getting the results. But the results are going full width and I can not find a css to lock them in the site. It also is not showing the sidebar even if I check the button. I know it is something in the theme but I can not change the theme. I can live without the side bar but I need to contain it in the width of the site .
