W=width; L=length=4W; P=perimeter=65 inches \n" ); document.write( "P=2(L+W) Substitute for L. \n" ); document.write( "65 ft=2(4W+W) \n" ); document.write( "65 ft=8W+2W \n" ); document.write( "65 ft=10W Divide each side by 10 \n" ); document.write( "6.5 ft=W ANSWER 1: Width is 6.5 feet. \n" ); document.write( "L=4W=4(6.5 ft)=26 feet ANSWER 2: Length is 26 feet. \n" ); document.write( "CHECK \n" ); document.write( "P=2(L+W) \n" ); document.write( "65 ft=2(26ft+6.5ft) \n" ); document.write( "65 ft=2(32.5 ft) \n" ); document.write( "65 ft=65 ft \n" ); document.write( " \n" ); document.write( " |
