16n+8=4
16n=4-8
16n=-4
n=-4/16
n=-1/4.
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
Answer:

If I'm wrong, im super sorry
Answer:
uhmm...
Step-by-step explanation:
<span>It is known that 1 mile = 1.609 kilometers. So the distance between these two cities, in kilometers, is equal to 140*1.609, which gives us ~225km.</span>
