How do you develop a formula for perimeter for a rectangle that has a width of y mi and Area = 2xy mi^2 ?
\n" ); document.write( ":
\n" ); document.write( "I understand it as:
\n" ); document.write( "Width = y miles, area = 2xy sq miles
\n" ); document.write( ":
\n" ); document.write( "Length is the area divided by the width:
\n" ); document.write( " $\"2xy%2Fy\"$ = 2x is the length:
\n" ); document.write( ":
\n" ); document.write( "Note that y canceled
\n" ); document.write( ":
\n" ); document.write( "Perimeter = 2L + 2W
\n" ); document.write( ":
\n" ); document.write( "P = 2(2x) + 2(y)
\n" ); document.write( ":
\n" ); document.write( "P = 4x + 2y \n" ); document.write( "
