Question 882141
Question almost looks like a rectangle problem.


You want x and y solutions.

{{{2x+2y=63}}}
{{{y=(63-2x)/2}}}
-
Substitute.
{{{x(63-2x)/2=65}}}
{{{x(63-2x)=130}}}
{{{-2x^2+63x-130=0}}}
{{{2x^2-63x+130=0}}}
D=(63)^2-4*2*130=3969-1040=2929=101*29
{{{highlight(x=(63+- sqrt(2929))/(2*2))}}}
The results for x will be positive either way, so you might expect y to be the other value; the PLUS form is one dimension and the MINUS form is the other dimension.  


You can finish from that.
