yeah, doesn’t require rocket science

#

Alr, what have you tried?

Welll not so much Only like the drawing and the data

#

#

I think this is figure I'm not sure

Ah wait, my drawing is incorrect

#

A second

#

are you sure you have written the question correctly? AF does not seem to bisect BE

#

Yeah, I wrote it wrong, you were right I confused the symbol

split flint Yeah, I wrote it wrong, you were right I confused the symbol

Hint:
If AF is perpendicular to BE then:

Area of ABFE
= ½×AF×BE
= Area of AFB + Area of AFE

Yeah, but is by congruence

split flint Yeah, but is by congruence

oh right

Oh, i think my construction is wrong i think is this
