L = 2w - 5
\n" ); document.write( "Lw = 52
\n" ); document.write( "---
\n" ); document.write( "Lw = 52
\n" ); document.write( "(2w - 5)w = 52
\n" ); document.write( "2ww - 5w - 52 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=-5 and c=-52
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "2 -5 -52

\n" ); document.write( "---
\n" ); document.write( "the quadratic has two real roots at:
\n" ); document.write( "---
\n" ); document.write( "w = 6.5
\n" ); document.write( "w = -4
\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( "w = 6.5
\n" ); document.write( "L = 2w - 5
\n" ); document.write( "L = 2*6.5 - 5
\n" ); document.write( "L = 8
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "w = 6.5 m
\n" ); document.write( "L = 8 m
