In the landscape environment, the number of pages appears in the left-hand side of the page. This is while I want to force LaTeX to print all the page numbers at the bottom. The following code is the MWE of my intended LaTeX. Please help me out to resolve this problem.
\documentclass[a4paper,11pt]{article}
\usepackage{pdflscape}
\usepackage{graphicx}
\usepackage{subcaption}
\begin{document}
\begin{landscape}
\begin{figure}
\centering
\begin{subfigure}[t]{0.7\textwidth}
\includegraphics[width=\linewidth]{Figure4a.pdf}
\caption{Positive decision variables}\label{Fig4a}
\end{subfigure}
~
\begin{subfigure}[t]{0.7\textwidth}
\includegraphics[width=\linewidth]{Figure4b.pdf}
\caption{Binary decision variables}\label{Fig4b}
\end{subfigure}\\[1ex]
\caption{XXX}
\label{Fig1}
\end{figure}
\end{landscape}
\end{document}
