Detailed Solution

Given that the point P is moving close to diagonals when compared with axes To understand the situation, consider the movement of the point P in the first quadrantThe point P is close to diagonal means it will not move the area below the ray which makes 22.5 degrees angle with x - axis and the point P does not move above the line which makes an angle 67.5 degrees with x - axis The shaded region is the region where the point P moves in the first quadrantsimilarly in all other quadrants tooA=4 times the above shaded region=42Area of triangle OAB−Area of triangle OAP=81211−1212−1=41−2+1=42−2=2.343A=2
