Trip down memory lane!

That tested my memory!

Approximately correct.

Assuming you have the exact answer and were just rounding, we will call this one solved.

Anyone want to post the solution and exact answer?

Ethylhexanediol, according to Wikipedia. Discontinued in 1991 due to some evidence of causing developmental defects in animals. I was sprayed with it a lot when young. Maybe that is ...

I got the long side as

1.5+sqrt(3.5^2-2.5^2)+sqrt(5^2-1)+3=1.5+2.5+4.9+3=11.9.

Correct!

But as John correctly pointed out, 6-12 is much better branding than 6-11.9 ;-)

Your formula gives the exact result. Pythagoras to the rescue!
