Question 1023827
Dimensions of a rectangle can be found when given its perimeter and its area.  Will such results match your first sentence description relating width and length?


{{{system(wL=40,2w+2L=26)}}}


{{{system(wL=40,w+L=13)}}}
{{{L=13-w}}}


{{{w(13-w)=40}}}

{{{13w-w^2-40=0}}}

{{{-13w+w^2+40=0}}}


{{{w^2-13w+40=0}}}
Discriminant is  {{{169-4*40=169-160=9=3^2}}}


{{{w=(13+- 3)/2}}}
And these are also the dimensions:  {{{highlight(system(w=5,OR,w=8))}}}.


YES.  The two dimensions differ by 3, and the LENGTH would be the even number value, 8; and width is 5.
