Question 1166193
{{{0.10(40)(50)=2000/10=200}}}-----the resulting area wanted


If the uniform strip to cut is x feet, then 
{{{(40-2x)(50-2x)=200}}}
and this to solve may be as simple as looking for the right factors of 200,... worth a try.


Or first a simplification
{{{2*2*(20-x)(25-x)=2*2*50}}}
{{{(20-x)(25-x)=50}}}
