The equation for the perimeter of a square is P=4d where d is the length of one side

To find the distance between two points on a cartesian plane you use the distance formula

$$d = \sqrt((x2-x1)^2+(y2-y1)^2)$$

$$d = \sqrt((5-1)^2+(-1-4)^2)$$Where B is (x2,y2) and A is (x1,y1)

sqrt(41) is about  6.4

so we plug that into the perimeter equation and get P=25.6
