If |z| = 3, the area of the triangle whose vertices are z, wz and z + wz (where w is a complex cube root of unity) is

Sure, let's solve the problem step by step.

Step 1: Given that |z| = 3, we know that z lies on a circle with radius 3 centered at the origin.

Step 2: Let's find the complex cube root of unity, denoted as w. The cube roots of unity are 1, e^(2πi/3), and e^(4πi/3). So, w can be any of these three values.

Step 3: Now, we need to find the vertices of the triangle. The vertices are z, wz, and z + wz.

Step 4: Let's consider the first vertex, z. Since |z| = 3, z lies on the circle with radius 3 centered at the origin.

Step 5: For the second vertex, wz, we multiply z by w. This gives us a new complex number, which we can represent as r*e^(iθ), where r is the magnitude and θ is the argument.

Step 6: Finally, for the third vertex, z + wz, we add z and wz together.

Step 7: Once we have the three vertices, we can calculate the area of the triangle using the formula for the area of a triangle in the complex plane.
