Yes, I did. Took me a couple of minutes.

Looking at your riddle,the lowest number should be the second number. I guessed a 1 would be there, it gave me a starting point to work out all the other numbers using your clues.

Which triangle has a bigger area: 1. A triangle with sides measuring 300, 400, and 500. 2. A triangle with sides measuring 300, 400, and 700.

3,4,500 is bigger. Just worked it out on a piece of paper.
