A rough sketch shows a square, of side L, with 5 rectangles inside, each L by L/5
\n" ); document.write( ".
\n" ); document.write( "Perimeter of rectangles = 2L +2(L/5) = 2.4 L = 30,,,,L= 12.5
\n" ); document.write( ".
\n" ); document.write( "Perimeter of square = 4*L=4*12.5 = 50 units
\n" ); document.write( ".
