 Hi and how are you all today? My name is Priyanka and the question to discuss says, in a huge park, people are concentrated at three points A, B and C, A where there are different slides and swings for children, B near which a man-made lake is situated and C which is near to a large parking and exit. Where should an ice cream parlor be set up so that maximum number of persons can approach it? Now this is the figure 7.5 to which we needed to refer. Now these are the three points which we have discussed. What we need to do is, we need to situate an ice cream parlor so that the maximum number of people can approach it that will be somewhere in the center. So first of all what we need to do is, we need to join A to B and B to C and C to A. That means we need to make a triangle first, like this. Now let me write down the steps also side by side. The first step was to draw a triangle let's say or join to form a triangle A, B, C. Then the second step is to construct perpendicular bisectors of any two sides let it be A, B and AC and let them intersect at point O. Like you know how to construct a perpendicular bisector now as it was explained to you in the first question also. So I am just drawing the perpendicular bisectors you will be drawing it in your copies with the help of like this I have drawn both the perpendicular bisectors for A, B and AC respectively let them intersect at point O. Now join O to B, B to A to O and O to C and measure that the distance will be same for each of them. So the third step will be join O, A, O, B measure them you will find the length of O, A is equal to O, B is equal to O, C. Let's say will be thus the ice cream parlor located or at the circum center that is O the triangle A, A, B, C so that it is E. So this is our required answer I hope you understood it well take care and bye for now.
