    Hello, Dragon!

    The areas of these two adjacent squares are 4cm² and 196cm².
    Find the length of the segment joining the centers of their inscribed circles.

    The sides of the squares are 2 cm and 14 cm.
    . . Then the radii of the circles are 1 cm and 7 cm.

    The central figure looks like this:
    Code:
        A *
          |  *
          |     *
         6|        *
          |           *
          |              *
        E + - - - - - - - - * B
         1|                 |1
          * - - - - - - - - *
         D         8         C

    We have right triangle AEB with AE = 6,\:EB = 8

    Using Pythagorus: . AB = 10
