W=width; L=length=4W+6in; P=perimeter=162in \n" ); document.write( "P=2(L+W) \n" ); document.write( "162in=2(4W+6in+W) Divide each side by 2. \n" ); document.write( "81in=5W+6in Subtract 6in from each side. \n" ); document.write( "75in=5W Divide each side by 5 \n" ); document.write( "15in=W ANSWER 1: The width is 15 inches. \n" ); document.write( "L=4W+6in=4(15in)+6in=60in+6in=66in ANSWER 2: The length is 66 inches. \n" ); document.write( "CHECK: \n" ); document.write( "P=2(L+W) \n" ); document.write( "162in=2(66in+15in) \n" ); document.write( "162in=2(81in) \n" ); document.write( "162in=162in \n" ); document.write( " |
