Renamed the topic, edited the question and added the OA.

Attached is a problem I was given in a GMAT test booklet. Although I have the answer, I still can't figure it out.
It says, in the diagram below, if the area of the tirangle LNP is 32, then what is the area of triangle LMN? The figure in my book is not drawn to scale.

I got \(24sqrt(2)\)
given area of LNP = \((1/2) NP * LP\) = 32 ==> LP = 8
using pythagorean theorem \(LN^2=LP^2+NP^2\)
==> LN = \(sqrt(64+64) = 8sqrt(2)\)
area of LMN =\((1/2) LN * MO\)= \((1/2) * 8 sqrt(2) * 6 = 24 sqrt (2)\)

same for me \(24sqrt2\)
