Ok, I'm scratching my head over this one. We were just watching "Are you smarter than a 5th grader" and I can't imagine that they didn't get challenged on this question.
The sides of a triangle are 5, 5, and 6. What is the area?
Now the guy thought it over and went with the cheat to use the kid's answer, which was wrong. When he had answered the question, then they put a picture up on the board showing the triangle with sides of 5, 5, and 6, and a dotted line showing the height to be 4. My brain was fried trying to figure out how they got the 4. After considerable internet searching, I have concluded (tell me if this is wrong) that the "Heron's Formula" that gives the height of 4 from the three side measurements is high school algebra. If they had shown the height as part of the question, that is elementary math (it was a 4th grade question). Am I crazy here?
