Answer Key / Explanation : (d) -

(d)

And  

When  is equidistant from  and , or  lies on angle bisector of lines  and . Hence, when , point  is nearer to  than  or lies below bisector of  and . Similarly, when  is nearer to  than , or lies below bisector of  and . Therefore, the required area is equal to the area of

Now,

Hence, triangle is equilateral. Then  coincides with centroid, which is

Therefore, area of  is  sq. units
