Algebra.Com's Answer #460896 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Perimeter = 2*length + 2*width \n" ); document.write( "Perimeter = 2*(x + 40) + 2x \n" ); document.write( "200yds = 2x + 80 + 2x \n" ); document.write( " 4x + 80 = 200 \n" ); document.write( " 4x = 200 - 80 \n" ); document.write( " 4x = 120 \n" ); document.write( " x = 30. \n" ); document.write( "Length = 70yds \n" ); document.write( "Width = 30yds \n" ); document.write( "Perimeter = 2*length + 2*width \n" ); document.write( " = 2*70 + 2*30 \n" ); document.write( " = 200yds. \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " \n" ); document.write( " |
