I stuck at the point where I had to find `a` and `b`:
```
a = 62791383142154.0
b = ?
c = ?
d = (a * a + b * b) - c * c
e = sqrt(4.0 * a * a * b * b - d * d) / 4
f = ((e + e) / (a + b + c)) - 19400354808065.54296875
g = ((a * b * c) / (e * 4.0)) - 47770539528273.90625000

a < b
b < c
c < a + b
-0.00001000 < f < 0.00001000
-0.00001000 < g < 0.00001000
```
Can someone please tell me how it could be solved or what was the other solution for this task?
