Let 
be the short, medium and long side, respectively. If we translate all the information into formulas, we get the following system:
Using the second equation, we can express the middle side in terms of the small one, and reduce the system to two equations in two unknowns:
And thus
But then again, using the first equation, the third becomes
So, the longest side is 12. Since the small is half the long, we have 
. Finally, the medium is three more of the small, so we have 
Answer:
Step-by-step explanation:
The answer is five because the meaning of median is middle and the number 5 is in the iddle
0.5h(115 + 85) = 6550
0.5h(200) = 6550
100h = 6550
h = 655 cms
height is 655 cms
50% is 30, it’s half of 60. 25% is the same as dividing by 4, 60/4 is 15.
