(3x – 1)cm + (4x + 2)cm + (2x – 5)cm = 122cm
\n" ); document.write( "9x = 126
\n" ); document.write( "x = 14cm\r
\n" ); document.write( "\n" ); document.write( "length of the longest side (4x+2) = 58cm
\n" ); document.write( "and checking...
\n" ); document.write( "41 + 58 + 23 = 122cm
\n" ); document.write( "
\n" );
