a square and a rectangle have the same area.
\n" ); document.write( "the square has side length 8 in.
\n" ); document.write( "square area = 8^2 = 64 sq/in
\n" ); document.write( " the length of the rectangle is four times its width.
\n" ); document.write( "L = 4w
\n" ); document.write( "L * w = 64
\n" ); document.write( "Replace L with 4w
\n" ); document.write( "4w * w = 64
\n" ); document.write( "4w^2 = 64
\n" ); document.write( "w^2 = 64/4
\n" ); document.write( "w^2 = 16
\n" ); document.write( "w = \"sqrt%2816%29\"
\n" ); document.write( "w = 4 in
\n" ); document.write( "I'll let you find the Length (4w)
\n" ); document.write( ":
\n" ); document.write( "what is the length of the rectangle
\n" ); document.write( "
