Perimeter = 2L+2W
\n" ); document.write( "2(2x+3)+2(0.5(x+3)) = 49
\n" ); document.write( "4x+6+x+3 = 49 add on left
\n" ); document.write( "5x+9 = 49
\n" ); document.write( "5x = 40
\n" ); document.write( "x = 8
\n" ); document.write( "-----------------
\n" ); document.write( "Check:
\n" ); document.write( "2(8)+3 = 19
\n" ); document.write( "0.5*(8+3) = 5.5
\n" ); document.write( "Perimeter:
\n" ); document.write( "2L+2W = 2(19)+2(5.5) = 39+10 = 49 Correct
