Hi there,
\n" ); document.write( "Small rectangle:
\n" ); document.write( "Area = 12 cm^2
\n" ); document.write( "Length = 4 cm.
\n" ); document.write( "Area = Length x Width
\n" ); document.write( "Width = Area/Length
\n" ); document.write( "Width = 12/4
\n" ); document.write( "Width = 3cm.
\n" ); document.write( ".........
\n" ); document.write( "Putting 6 small rectangles
\n" ); document.write( "together to make one large
\n" ); document.write( "rectangle.
\n" ); document.write( "I have placed them in two rows
\n" ); document.write( "of 3.
\n" ); document.write( "Length of large rectangle
\n" ); document.write( "= 3 x 4 = 12 cm
\n" ); document.write( "Width of large rectangle
\n" ); document.write( "= 2 x 3 = 6
\n" ); document.write( "Area = Length x Width
\n" ); document.write( "Area = 12 x 6
\n" ); document.write( "Area = 72 cm^2
\n" ); document.write( "..........
\n" ); document.write( "Perimeter of large rectangle:
\n" ); document.write( "Perimeter = 2 x Length + 2 x Width
\n" ); document.write( "Perimeter = 2 x 12 + 2 x 6
\n" ); document.write( "Perimeter = 36 cm.
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
\n" );
