Coordinates

To find the perimeter, we must first find the distance from (1, -2) to  (4, -10). To do this, we can use the distance formula.

$\sqrt((x\delta)^2+(y\delta)^2),$ where $\delta$=the change in positioning for the point.

We can plug in for this equation to get $\sqrt((4-1)^2+(-10--2)^2)$

Simplifying this, we get $\sqrt(3^2+(-8)^2)$, then $\sqrt(9+64)$, and finally $\sqrt73$

Since there are 4 sides to a square, multiply $\sqrt73$ by 4 to account for all sides.

The final answer should be $4\sqrt73$ since 73 is prime.
