\"x\"= length of the side of the painting (in feet).
\n" ); document.write( "\"x-2\"= length of the side of the mirror (in feet).
\n" ); document.write( "\"x%5E2\"= area of the painting (in ft squared).
\n" ); document.write( "\"%28x-2%29%5E2\"= area of the mirror (in ft squared).
\n" ); document.write( "The problem says that
\n" ); document.write( "\"%28x-2%29%5E2=x%5E2-32\" ,
\n" ); document.write( "because the difference of their areas is 32 ft squared,
\n" ); document.write( "and the mirror, with shorter sides, must have a smaller area.
