find the perimeter of the polygon with vertices A(5,3) B(1,0) C (3,4) D(3,7)

The distance between two given points P1(x1,y1) and P2(x2,y2) in the coordinate plane is given by the expression:
distance P1P2 = sqrt((x2x1)^2+(y2y1)^2)
A(5,3) B(1,0) C (3,4) D(3,7)
For example, the distance
AB = sqrt((1(5))^2+(0(3))^2)
= sqrt(6^2+3^2)
= sqrt(45)
= 6.708...(approx.)
Proceed the same way for BC, CD and CA and add up the four distances to get the perimeter.
