l = 1500000
e = 12.5
r = 2
x = (l*l) * (e/r)

Result of x would be 14062500000000


so my question is now how to get "l" if i change "x"
i tried alot of things already but couldnt find a way to do it but there must be one
please let me know if anyone knows a way to get "l" if i change "x"

Thank you very much

$$x = I^2 * \left(\dfrac e r\right)$$

$$\left(\dfrac {r}{e}\right)*x=I^2$$

$$I=\sqrt{\left(\dfrac r e\right)*x$$

just plug your numbers for r, e, and x in.
