I am guessing that the width of the rectangle is equal to the sides of a square.
\n" ); document.write( "Side * Side = Area
\n" ); document.write( "w * w = a
\n" ); document.write( "w^2 = a
\n" ); document.write( "Also, the rectangle:
\n" ); document.write( "(w + 8)(w) = 160 + a
\n" ); document.write( "w^2 + 8w = 160 + a
\n" ); document.write( "w^2 + 8w - 160 = w^2
\n" ); document.write( "8w = 160
\n" ); document.write( "w = 20
\n" ); document.write( "Plug:
\n" ); document.write( "(w + 8) = length
\n" ); document.write( "20 + 8 = length
\n" ); document.write( "28 = length
\n" ); document.write( "Square: 20x20
\n" ); document.write( "Rectangle: 20x28 \n" ); document.write( "
\n" );
