x represent side length of a square .find a regular polygon with side length x
\n" ); document.write( " whose perimeter is twice the perimeter of the square.
\n" ); document.write( ":
\n" ); document.write( "4x = perimeter of original square
\n" ); document.write( "then
\n" ); document.write( "8x = twice the perimeter
\n" ); document.write( ":
\n" ); document.write( "let y = side of polygon with twice the perimeter
\n" ); document.write( "2x + 2y = 8x
\n" ); document.write( "Simplify, divide by 2
\n" ); document.write( "x + y = 4x
\n" ); document.write( "y = 4x - x
\n" ); document.write( "y = 3x
\n" ); document.write( "therefore
\n" ); document.write( "2x + 2(3x) = 8x
\n" ); document.write( "Polygon with twice the perimeter: 3x by x
\n" ); document.write( ":
\n" ); document.write( "find a regular polygon with side length x whose perimeter is three times
\n" ); document.write( " the length of the square
\n" ); document.write( "this perimeter: 3(4x) = 12x
\n" ); document.write( "let y = side of polygon with three times the perimeter
\n" ); document.write( "2x + 2y = 12x
\n" ); document.write( "Simplify, divide by 2
\n" ); document.write( "x + y = 6x
\n" ); document.write( "y = 6x - x
\n" ); document.write( "y = 5x
\n" ); document.write( "therefore
\n" ); document.write( "2x + 2(5x) = 12x
\n" ); document.write( "Polygon with three times the perimeter: 5x by x
\n" ); document.write( " \n" ); document.write( "
\n" );
