Six housing subdivisions within a city area are target for emergency service by a centralized fire station. Where should the new fire station be located such that the maximum rectilinear travel distance is minimized? Assume that the total value of the homes in each sub-division is equal. The centroid locations (in miles) are as follows:
Subdivsion x-coordinate y-coordinate Total Vaue (in millions)
A 20 15 50
B 25 25 120
C 13 32 100
D 25 14 250
E 4 21 300
F 18 8 75

Explanation:

Since there are six points, the minimum distance from all points would be the centroid of polygon formed by A,B,C,D,E,F

To find the coordinates of centroid of a polygon we use the following formula. Let A be area of the polygon.

    where i=1 to N-1 and N=6

A area of the polygon can be found by the following formula where i=1 to N-1

A=0.5[(20×25 -25×15) +(25×32 -13×25)+(13×21 -4×32)+(4×8 -18×21)+(18×14 -25×8)

A=225.5 miles²

Now putting the value of area in Cx and Cy

putting the values of x's and y's you will get

For Cy

putting the values of x's and y's you will get

So coordinates for the fire station should be (15.36,22.55)

do you have any options?
