U can use Pythagoras theorem
(25-20)²+12²=25+144=169
√169=13
so 13 m is the distance between their tops

From the given diagram:
by pythagoras theorem,
distance between tops=(5^2+12^2)^1/2
                                =(25+144)^1/2
                                =169^1/2=13
therefore,distance b/w their tops is 13 m.
