1.	If \|z2+iz1\|=\|z1\|+\|z2\| and \|z1\|=3 and \|z2\|=4, then area of △ABC, if affixes A,B and C are z1,z2 and (z2−iz11−i) respectively, is
Answer» If $\| z_{2} + i z_{1} \| = \| z_{1} \| + \| z_{2} \|$ and $\| z_{1} \| = 3$ and $\| z_{2} \| = 4$ , then area of $△ A B C$ , if affixes $A, B$ and $C$ are $z_{1}, z_{2}$ and $(\frac{z_{2} - i z_{1}}{1 - i})$ respectively, is
