You can put this solution on YOUR website!
L=3W-2 I'M ASSUMING YOU MEAN THE WIDTH OF THE RECTANGLE NOT THE TRIANGLE(?).
\n" ); document.write( "L*W=AREA
\n" ); document.write( "(3W-2)W=65
\n" ); document.write( "3W^2-2W-65=0
\n" ); document.write( "(3W+13)(W-5)=0
\n" ); document.write( "W-5=0
\n" ); document.write( "W=5 FOR THE WIDTH.
\n" ); document.write( "L=3*5-2=15-2=13 FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "5*13=65
\n" ); document.write( "65=65
\n" ); document.write( " \n" ); document.write( "
