Missing info in the question. Question is solvable, but not at P6 level if base is not given.

You can let the base of the unshaded triangle √31 cm

welcome. It's commendable that you know Pythagoras' Theorem at P6 (it's a secondary 2 topic)

Thanks but this is wrong. 20 is entire length of big triangle, not just shaded portion only
