i.e area of rectangle = length * width.

For square length and width values are same.

i.e if length = s and width=s then  area of square = s*s

To print the rectangle Pattern with * we need length and width values.

   for (int i = 1; i <=width ; i++)
   {
    for (int j = 1; j <= length; j++)
    {
     if(i==1 ||i==width  ||j==1 ||j==length )
     {
