If the area of the triangle on the complex plane formed by the points

z,\;z + iz

and

iz

is 200, then the value of

\left| {3z} \right|

must be equal to

View answer and explanation

Correct option: C

Option C (60) is correct because the area of the triangle is related to |z|^2, and given the area is 200, we can find |z| and then |3z|.
