Okay, so now I understand the problems the girl has. The math questions are stupid. Really. You know that a door is 9 feet tall and 5 feet wide, and a second door with a similar rectangle is 4 feet tall, so how wide is the second door?

The real answer has got to be, why the f--k didn't the idiot who measured the second door's height measure the width? And what idiot hired him?
