L=length=2W-4; W=width; P=perimeter=2(L+W)
\n" ); document.write( "P=2(L+W) Substitute for L, enter given value for P
\n" ); document.write( "46 cm=2(2W-4+W)
\n" ); document.write( "46 cm=2(3W-4)
\n" ); document.write( "46 cm=6W-8 Add 8 to each side
\n" ); document.write( "54 cm=6W Divide each side by 6
\n" ); document.write( "9 cm=W
\n" ); document.write( "ANSWER Width of the rectangle is 9 cm.
\n" ); document.write( "CHECK
\n" ); document.write( "L=2W-4=18-4=14 cm
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "46 cm=2(14 cm+ 9 cm)
\n" ); document.write( "46 cm=2(23 cm)
\n" ); document.write( "46 cm=46 cm
\n" ); document.write( "
\n" ); document.write( "
