AREA=L*W
\n" ); document.write( "L=W+3
\n" ); document.write( "2,160=(W+3)W
\n" ); document.write( "2,160=W^2+3W
\n" ); document.write( "W^2+3W-2,160=0
\n" ); document.write( "(W+48)(W-45)=0
\n" ); document.write( "W-45=0
\n" ); document.write( "W=45 ANS. FOR THWE WIDTH.
\n" ); document.write( "L=45+3=48 ANS. FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "2,160=45*48
\n" ); document.write( "2,160=2,160
\n" ); document.write( "P=2L+2W
\n" ); document.write( "P=2*48+2*45
\n" ); document.write( "P=96+90
\n" ); document.write( "P=186 ANS. FOR THE PERIMETER.
