Given that CDEF is a parallelogram
So, every two opposite sides are equal in length
And the diagonals bisect each other
So, CD = FE , CF = DE , CG = EG and FG = DG
so,
[tex]\begin{gathered} CF=DE=10 \\ \\ FE=CD=15 \\ \\ CE=2\cdot CG=2\cdot7=14 \\ \\ GD=\frac{1}{2}FD=\frac{1}{2}\cdot22=11 \end{gathered}[/tex]
