the perimeter of the square is equal to 4w.
\n" ); document.write( "the perimeter of the rectangle is equal to 2l + 2w
\n" ); document.write( "l is equal to 5w.
\n" ); document.write( "the perimeter of the rectangle is equal to 2*5w + 2w
\n" ); document.write( "the perimeter of the rectangle is equal to 12w
\n" ); document.write( "the sum of the perimeter is equal to 4w + 12 w = 16w
\n" ); document.write( "the sum of the perimeters is equal to 112 cm.
\n" ); document.write( "w is equal to 112 / 16 = 7
\n" ); document.write( "l is equal to 5 * 7 = 35
\n" ); document.write( "perimeter of square is equal to 4*7 = 28
\n" ); document.write( "perimeter of rectangle id equal to 2*35 + 2*7 = 70 + 14 = 84.
\n" ); document.write( "sum of the perimeters is equal to 28 + 84 = 112.\r
