W=width; L=length=2W-5cm; P=perimeter=2(L+W)=116cm
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "116cm=2(L+W) Divide each side by 2.
\n" ); document.write( "58cm=L+W Substitute for L.
\n" ); document.write( "58cm=2W-5cm+W Add 5cm to each side.
\n" ); document.write( "63cm=3W Divide each side by 3.
\n" ); document.write( "21cm=W ANSWER 1:The width is 21 cm.
\n" ); document.write( "L=2W-5cm
\n" ); document.write( "L=2(21cm)-5cm=42cm-5cm=37cm ANSWER 2: The length is 37 cm.
\n" ); document.write( "
