I want to draw something like this picture:
As the shadow is curved, i decided to draw a trapezium and then draw a shadow on it. The problem is i want the coordinates of the trapezium corners. here is my code
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric}
\usetikzlibrary{shadows}
\usetikzlibrary{shapes.symbols}
\definecolor{mycolor}{rgb}{0.55,0.9,0.55}
\begin{document}
\begin{tikzpicture}[y=.3cm, x=1.2cm,font=\sffamily]
%\node[circle,fill=black] at (0,0) {};
\node[circle,fill=black] at (5.59,-8.3) {};
\node[circle,fill=black] at (-2.1,-8.3) {};
\node[circle,fill=black] at (-5.59,8.3) {};
%rotate = -140
\node[trapezium, minimum width=10cm,trapezium left angle=130, trapezium right angle=50, minimum height = 5cm,fill=mycolor] at (0,0){};
\filldraw[fill=gray]
(5.55,-8.3) -- (5.55,-8) -- (-2.1,-8) -- (-5.6,8) -- (-5.59,8.3) -- (-2.1,-8.3) -- cycle;
\end{tikzpicture}
\end{document}
I tried to figure out the coordinates by drawing circles in the arbitrary locations and correct them manually.
Is there away to find these coordinates accurately?, and am i thinking a hard way and there is an easy way to do this?.
