The side of the square = 84/4 = 21cm \n" ); document.write( "The perimeter of the rectangle = 84/3 = 28cm \n" ); document.write( "Perimeter = 2 lengths + 2 breadths \n" ); document.write( " 2 lengths + 2 breadths = 28 cm \n" ); document.write( " 2 x 8 cm + 2 breadths = 28 cm \n" ); document.write( " 2 breadths = 28 cm - 16 \n" ); document.write( " breadth = 6 cm\r \n" ); document.write( "\n" ); document.write( "Therefore difference between the breadth of the \n" ); document.write( "rectangle and the side of the square is:\r \n" ); document.write( "\n" ); document.write( " 21cms - 6cms = 15 cms \n" ); document.write( " |
