  1. A \(\frac{1}{2}+\sqrt{3} i\)
  2. B \(\frac{\sqrt{5}+\sqrt{3} i}{4}\)
  3. C \(\frac{3}{2}+\frac{\sqrt{3} i}{2}\)
  4. D \(\frac{\sqrt{3}+\sqrt{11} i}{2}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\frac{1}{2}+\sqrt{3} i\)

Step-by-step Solution

Detailed explanation

Let \(z=x+i y\) Then, vertices of rectangle are \((x, y),(x,-y)\), \((-x,-y),(-x, y)\). Now, area of rectangle \(=(2 x)(2 y)=4 x y\) It is given that,…
