perimeter equals 1200 feet.
\n" ); document.write( "shortest side is equal to x.
\n" ); document.write( "one side is 200 feet longer than the shortest side, so it is equal to x + 200
\n" ); document.write( "another side is 400 feet longer than the shortest side, so it is equal to x + 400
\n" ); document.write( "perimeters equals the sum of all 3 sides, so the perimeter is equal to:
\n" ); document.write( "x + x + 200 + x + 400 which is equal to:
\n" ); document.write( "3x + 600.
\n" ); document.write( "since the perimeter is equal to 1200 feet, then we get:
\n" ); document.write( "3x + 600 = 1200
\n" ); document.write( "subtract 600 from both sides of the equation to getr:
\n" ); document.write( "3x = 600
\n" ); document.write( "divide both sides of the equation by 3 to get:
\n" ); document.write( "x = 200
\n" ); document.write( "shortest side is equal to 200
\n" ); document.write( "next shortest side is equal to 400
\n" ); document.write( "next shortest side is equal to 600
\n" ); document.write( "add them up together and you get 1200.
\n" ); document.write( "second shortest side is 200 more than the shortest side.
\n" ); document.write( "longest side is 400 more than the shortest side.
\n" ); document.write( "requirements of the problem have been satisfied.\r
