You have to first mess around with the first shape, ABCD, and split that into a rectangle and a right triangle. once you do that, it's pretty painstaking, but simple.

if you look at it you can tell that EFGH is just half the size, but the same ratios and everything.

So, you would just take every perimeter measurement from ABCD, and divide it by two and then sum them together.

2.5 + 1.5 + 4.0 + 2.0 = 10

Hey there!

To start, you must use the distance formula which is $\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }$ .

x1 and x2 are the x coordinates of the points (it does not matter which one you assign to be x1 and x2) and y1 and y2 are the y coordinates (also does not matter which one you assign to be y1 and y2).

Now, set up your formula and simplify:

$\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }$

$\sqrt{(-12-13)^{2}+(6-8)^{2} }$
