The perimeter of the rectangular playing field is 310 m.

The length is 65 meters more than the width.

Let L represents the length and W represents the width of the playing field.

Recall that the perimeter of a rectangular shape is given by

Substitute the value of perimeter and length into the above formula

$\begin{gathered} P=2(L+W) \\ 310=2(65+W+W) \\ 310=2(65+2W) \\ 310=130+4W \\ 310-130=4W \\ 180=4W \\ (180)/(4)=W \\ 45=W \\ W=45\: m \end{gathered}$

So, the width is 45 m.

$\begin{gathered} L=65+W \\ L=65+45 \\ L=110\: m \end{gathered}$

So, the length is 110 m.
