Let the lenght and width of the smaller rectangle be given by l and w.
\n" ); document.write( "You are told the larger rectangle sides are 4x larger. so they are (4l) and (4w).
\n" ); document.write( "Area is given by length * width.
\n" ); document.write( "Area of the smaller rectangle is $\"lw+=+40\"$
\n" ); document.write( "Area of the larger rectangle is $\"4l+%2A+4w+=+16%2Alw\"$
\n" ); document.write( " $\"AreaOfLarger+=+16%2Alw+=+16%2A40+=+640+\"$ square inches
\n" ); document.write( " \n" ); document.write( "
