L=2W+3
\n" ); document.write( "W(2W+3)=93
\n" ); document.write( "2W^2+3W-93=0
\n" ); document.write( "USING THE QUADRATIC EQUATION:\"x=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29\" WE GET:
\n" ); document.write( "W=(-3+-SQRT[3^2-4*2*-93])/2*2
\n" ); document.write( "W=(-3+-SQT[9+744])/4
\n" ); document.write( "W=(-3+-[SQRT753])/4
\n" ); document.write( "W=(-3+-27.44)/4
\n" ); document.write( "W=(-3+27.44)/4
\n" ); document.write( "W=24.44/4
\n" ); document.write( "W=6.11 ANSWER FOR THE WIDTH.
\n" ); document.write( "L=2*6.11+3=12.22+3=15.22 ANSWER FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "6.11*15.22=93
\n" ); document.write( "92.99~93
\n" ); document.write( "
\n" );
