Question 1037750
<pre>
Length       (5p-6)m
Width        (p+4)m
Perimeter    20m
</pre>


Using formula for perimeter of a rectangle,  {{{2(5p-6)m+2(p+4)m=20m}}}
and then simplify this one equation.
{{{5pm-6m+p+4=10m}}}
{{{5pm-6m+4-10m=0}}}
{{{5pm-16m+4=0}}}------------No way to find the dimensions.  This is a nonlinear equation in two variables, m and p.

WRITE YOUR DESCRIPTION CORRECTLY SO IT IS UNAMBIGUOUS.
The results you want are length is {{{(3&1/6)*METERS}}}  and width is {{{(5&5/6)METERS}}}.
