Answer & Solution

Correct Answer

(C) \(36\)

Step-by-step Solution

Detailed explanation

Clearly for the shaded region \(z_1\) is the intersection of the circle and the line passing through \(\mathrm{P}\left(\mathrm{L}_1\right)\) and \(\mathrm{z}_2\) is intersection of line \(\mathrm{L}_1 \& \mathrm{~L}_2\) Circle : \((x+2)^2+(y-3)^2=1\) \(L_1: x+y-1=0 \)…
