Let the width of the border be x ft.
\n" ); document.write( " Since the outer rectangular should be of dimensions 2x+29 and 2x+44.
\n" ); document.write( " The area of the border = Area (outer rectangular -inner rectangular)
\n" ); document.write( " We have (2x+29)(2x+44) - 29*44 = 474,
\n" ); document.write( " Simplify: 4x^2 + 146 x = 474
\n" ); document.write( " Or 2x^2 + 73 x - 237 = 0,
\n" ); document.write( " Factoring (2x +79) (x -3) = 0 [Note: 237 =3 * 79]
\n" ); document.write( " So, x = 3 or -79/2 (negative ,invalid)\r
\n" ); document.write( "\n" ); document.write( " Answer: The uniform width of the border is 3 ft\r
\n" ); document.write( "\n" ); document.write( "
