Options
- A. 1 2 + 3 i
- B. 5 + 3 i 4
- C. 3 2 + 3 i 2
- D. 3 + 11 i 2
Answer
A. 1 2 + 3 i
Step-by-step solution
Let a complex number, z=x+i y z = x -i y Then, vertices of rectangle for z, z ,-z,- z are (x, y),(x,-y),(-x,-y),(-x, y) Now, Area of rectangle =(2 x)(2 y)=4 x y It is given that, Area =2 3 =4 x y 2 x y= 3 x= 1 2 , y= 3 z= 1 2 + 3 i
