You can put this solution on YOUR website!
the equation for perimeter is p = 2L + 2w. If you let w represent the width, then you can make the equation:
\n" ); document.write( "(166) = 2(3w-13) + 2(w)\r
\n" ); document.write( "\n" ); document.write( "then isolate w\r
\n" ); document.write( "\n" ); document.write( "166 = 6w - 26 + 2w
\n" ); document.write( "192 = 8w
\n" ); document.write( "24 = w
\n" ); document.write( "
\n" ); document.write( "Therefor, the width is 24inches
\n" ); document.write( "
\n" );
