Let the length of the longer piece = $\"a\"$
\n" ); document.write( "The length of the shorter piece = $\"+%281%2F2%29%2Aa+\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"+a+%2B+%281%2F2%29%2Aa+=+15+\"$
\n" ); document.write( "Multiply both sides by $\"2\"$
\n" ); document.write( " $\"+2a+%2B+a+=+30+\"$
\n" ); document.write( " $\"+3a+=+30+\"$
\n" ); document.write( " $\"+a+=+10+\"$
\n" ); document.write( " $\"%281%2F2%29%2Aa+=+5+\"$
\n" ); document.write( "The longer piece is 10 m
\n" ); document.write( " \n" ); document.write( "
