I forgot too, but thankfully I realised after reading the formula a couple times

The matrix multiplication kata you did is absurdly overranked.

Please take a look at this updated version for more clarity.

oh, you're quite near all right.

ignore the edge cases first. (e.g. where sides are undefined/complex)

try writing out a series of simultaneous equations for the side lenghts of the triangle.

i'm afraid i can't really give you any more hints though, as that would make the solution too obvious already.

however, if i were in your shoes, i would try asking someone else, like a friend or a teacher/professor, see if they can help a little bit.

remember, this is a right triangle. we can find the area of that quite easily, no?

however, if you don't know what Heron's formula is, I would really suggest reading up about it; it's quite simple to understand, and there's no harm in doing more research.

Good luck though, all the best!

• this problem only requires knowledge of basic algebra
• condense your code into 1 line and use a lambda expression.
• then a little bit of python magic can be used :)

It's actually very simple. If you don't know how the code works, try to follow it through a few examples, then everything should be clear. There are a few tricks used here.
