Talking Indecisive triangle - Crack This!

Puzzle Taken From - http://www.archimedes-lab.org/

If a = 23 units and the value of the sides of the green square is a multiple of 11, what is the area of the red scalene triangle? Hint: the area is a decimal number but is not irrational. Find the very shortest way to solve this puzzle and use only basic geometry, trigonometry is not allowed!



Get started, CEans
