Thought I did this right but apparently got it wrong

Attachment 23836

Two strips of cloth with width 1 overlap at an angle a as shown. Find the area of the overlap.

I swear I am missing something on this.

Rhombus Area is base x height

Height is 1

Let base = x

unknown angle a

So all I could come up with was:

Which gave me the Area = A

I don't recall ever figuring out an area with so little information given before.

If you submitted that answer to a human teacher/professor,

. . he/she would deduct points for the very same reasons.

You are saying, "Hey, I did all the *algebra!*"
