You can put this solution on YOUR website!
Let x = AD\r
\n" ); document.write( "\n" ); document.write( "Let 3x = AB\r
\n" ); document.write( "\n" ); document.write( "Let p = 16\r
\n" ); document.write( "\n" ); document.write( "16 = 2(3x) + 2x\r
\n" ); document.write( "\n" ); document.write( "Can you finish the problem now?
