Let the diagonal = $\"+c+\"$
\n" ); document.write( " $\"+c%5E2+=+8%5E2+%2B+16%5E2+\"$
\n" ); document.write( " $\"+c%5E2+=+64+%2B+256+\"$
\n" ); document.write( " $\"+c%5E2+=+320+\"$
\n" ); document.write( " $\"+c+=+17.889+\"$ ft
\n" ); document.write( " $\"+17.889+%2B+2%2A3+=+23.889+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+.889%2A12+=+10.66+\"$
\n" ); document.write( "The wire should be 23 ft 11 in long
\n" ); document.write( "check the math
