P=2(length + width) [formula for the perimeter of a rectangle]
\n" ); document.write( "Perimeter = 28
\n" ); document.write( "Length = (2w-1)
\n" ); document.write( "Width = w
\n" ); document.write( "28=2[(2w-1)+w) [plug-in the values]
\n" ); document.write( "28=2(3w-1)[simplify]
\n" ); document.write( "28=6w-2
\n" ); document.write( "28+2=6w
\n" ); document.write( "30/6=5=width
