Great!
why are you guys debating so much?
Do do in Slack or P.M. Don't comment unnecessarily
Do s in Slack or P.M. Don't comment unnecessarily
Comments can be used for an answer to discuss :P
Its not a debate, it a discussion
So.. Where I was.. I think it would not be the answer
If a + b + c = d + e + f, it ain't necessary that a² + b² + c² = d² + e² + f²
That's my confusion, or the data is insufficient.. Or we are doing something wrong.. Even my maths sir didn't figure it out yet :P

See the diagram.
The question is difficult to answer and requires complex calculations if the triangles are inclined as in the first figure.
It is easier if the bases BC and FE of the triangles are parallel... Then as all internal angles are 60 deg., AB || DE. and FD || AC.
Then we have parallelograms inside... In parallelograms opposite sides are equal. So
PQ = TS QR = UT PU = RS
Sum of the squares = 2² + 3² + 4² = 29 cm²
