Algebra.Com's Answer #5751 by askmemath(368)![]() ![]() ![]() You can put this solution on YOUR website! Let width =W \n" ); document.write( "Then length = 2W (since it's twice the width)\r \n" ); document.write( "\n" ); document.write( "Perimeter = 2(length+width) = 240 \n" ); document.write( "2(2W+W)= 240 \n" ); document.write( "2(3W)=240 \n" ); document.write( "6W=240 \n" ); document.write( "Dividing by 6 throughout \n" ); document.write( "W = 40 \n" ); document.write( "Length = 2W = 2x40 = 80 \n" ); document.write( " |
