The map is detailed so that the perimeter of the town is 5 times its original perimeter find the coordinate ?

Question

A(0.5,2), B2,3.5), C(5,1.5), and D(3,1)?

its original perimeter find the coordinate

Answer 1

i would pick out A for it that's the most important one  

Answer 2

Find the center by figuring the intersection

of the lines AC and BD.

AC: y = 185/90 - x/9

BD: y = 8.5 - 5x/2

Intersection is the point

(116/43, 8.5 - 5/2*116/43)

approximately (2.698, 1.756).

Then compute points A' B' C' D' which lie

on those lines at 5x the distance

of A, B, C, D from P.

Call the coordinates of P (x,y)

Then coordinates of A' are (x - (x-.05)*5, (y - (y-2)*5)

and similarly for B' C' D'
