weird or tough one :shock: I've tried to solve it looking from the top of the picture (imaging the 3D figure) but my answer was wrong :)

I got 3/4

Don't look at the figure and draw your own up from the description. I do not know if this is right either, but I did not see the figure until after calculating. Then when I saw the figure, re did my calculations I also got 1/2

I got 1/2 also. Since you know the length of 2 sides of the triangle BCE (which are both 1) that's all you should need to find the area (1/2 base * height). When you plug the numbers in you get 1/2 * 1 * 1 = 1/2.

Please let us know what the OA is! I want to know if I am just completely missing something here (wouldn't be the first time)...

ETA: Upon looking at it again, I can see perhaps that the lines I first thought were the base and height are not actually the base and height. Since they are sure to tell you that BE = DE, maybe it's one of those screwy supplementary angle or some such, problems. Hmmm...

How did u guys get 1/2 or 3/4. All I see is 2 congruent isosceles triangles BCE and DCE with 2 sides = 1 and the third side BE=CE. I am stumped to say the least
