F*** you, Mitsubishi. I don't like your cars anyway.
That was pretty much my answer also...

MadEngineer: I had this question from when I studied NZCE
surfisup1000:Jaxson: This took me about 10 seconds. How is this difficult?
That may sound knoby but I found that china (?) car parking sequence one WAY more difficult, and that was for 7 year olds...
87, not really a math question though. More a psychological trick.

That's a much more appropriate question to "test" students with IMHO :)
(BTW, I have determined the answer, but I haven't found an "elegant" way to solve it)

Surely that just goes to a quadratic equation which can be solved by the standard formula (answer =12)?

So multiply that lot out, make d the subject and therefore solve for d?

I'd approach it as Total area 108 m^2 is created by the area of the square plus the area of the Triangle.
So:
Area of the Square is d times (12d/2)
plus
Area of the triangle is (d times (12m  (12d/2))) / 2
=
108 So multiply that lot out, make d the subject and therefore solve for d?

Yep, it comes out as d^2 48d +432 = 0, and you can apply the standard quadratic formula from there
MadEngineer: It's not a square.
