thanks Captain Black,now it loks quite straight forward to me, so this means height of 32.4 doesnt play any part in calculating the area???

Given:

BE and CD are parallel

&

FD and GC are parallel

That implies that point G__CANNOT__be on the line BE.

If G were on the line BE then angle BGC (which is given as 82deg13min46sec) should equal angle GCD (which is indicated as 90degrees).

It really looks as if this is a "flawed" question.

That is, you are given invalid information for the purpose of understanding how you handle errors.

What data will you use and what information will you ignore? - Jul 23rd 2009, 03:22 PMCaptainBlack
