W=breadth; L=length=2W P=perimeter=2(L+W)=72m \n" ); document.write( "P=2(L+W) \n" ); document.write( "72m=2(L+W) Divide each side by 2 \n" ); document.write( "36m=L+W Substitute for L \n" ); document.write( "36m=2W+W \n" ); document.write( "36m=3W Divide each side by 3. \n" ); document.write( "12m=W ANSWER 1: The breadth is 12 meters. \n" ); document.write( "L=2W=2(12m)=24m ANSWER 2: The length is 24 meters. \n" ); document.write( "CHECK: \n" ); document.write( "P=2(L+W) \n" ); document.write( "72m=2(24m+12m) \n" ); document.write( "72m=2(36m) \n" ); document.write( "72m=72m \n" ); document.write( " \n" ); document.write( " |
