<PRE><B>Question 860283</B>
Let a triangle of sides 3,4,5 be such that the longest side is the base. Then the height is :
A 15/4 
B 20/3
C 16/5
D 12/5
E 9/4
------------
The easy way:
Using 4 as the base and 3 as the height, area = b*h/2 = 6
----
With 5 as the base:
Area = 5*h/2 = 6
h = 12/5
