How to end wrapfigure envirenment

I used wrapfigure when I want insert a figure, but can's stop it after the figure. I used the \begin{wrapfigure}[35]{r}{20cm}

\documentclass[landscape,12pt,a3paper]{article}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage[left=2.00cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\begin{document}

\setlength{\intextsep}{1cm}
\begin{wrapfigure}[35]{r}{20cm}
    \centering
    \includegraphics[width=20cm]{03-1.pdf}\\
\end{wrapfigure}

text text  text text  text text  text text  text text ........

\end{document}
