width=W, length=L=W+9
\n" ); document.write( "Perimeter P=2(L+W)=250 cm substitute for L
\n" ); document.write( "P=2(W+9+W)
\n" ); document.write( "250 cm=2(2W+9) divide both sides by 2
\n" ); document.write( "125 cm=2W+9 subtract 9 from each side
\n" ); document.write( "116 cm=2W divide each side by 2
\n" ); document.write( "58 cm=W, ANSWER 1 Width=58 cm
\n" ); document.write( "L=W+9=58 cm + 9cm= 67 cm ANSWER 2 Length = 67 cm
\n" ); document.write( "CHECK
\n" ); document.write( "perimeter=2(L+W)
\n" ); document.write( "250 cm=2(58cm+67 cm)
\n" ); document.write( "250 cm=2(125 cm)
\n" ); document.write( "250 cm=250 cm
