L = 2w + 20
\n" ); document.write( "Lw = 6000
\n" ); document.write( "---
\n" ); document.write( "Lw = 6000
\n" ); document.write( "(2w + 20)w = 6000
\n" ); document.write( "2ww + 20w - 6000 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=20 and c=-6000
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "2 20 -6000

\n" ); document.write( "w = 50
\n" ); document.write( "w = -60
\n" ); document.write( "---
\n" ); document.write( "the negative root doesn't fit the problem statement, so use the positive root:
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "w = 50 m
\n" ); document.write( "L = 120 m
