Hello,
\n" ); document.write( "We can set up the following equation as:
\n" ); document.write( "(W is width and W+3 is length)
\n" ); document.write( "2W+2(W+3)=42
\n" ); document.write( "Combine like terms:
\n" ); document.write( "4W+6=42
\n" ); document.write( "Subtract 65 and divide by 4 to get:
\n" ); document.write( "W=9 cm Now we know the length is:
\n" ); document.write( "L=12 cm
\n" ); document.write( "Make sense?
