anonymous · Answer

Looking at regular plane figures like that makes it easier to figure out their areas.

Any isosceles triangle can be split and flipped to form a rectangle, and many plane figures can be broken into isosceles triangles!  :-)

anonymous · Answer

Yup! That's a match to my calculation, too!  :-)

....wait....

Where did you get the ".4" in 1086.4 ?

anonymous · Answer

i did not get it that was the answer :) :P the test gave me :P

anonymous · Answer

Hogwash!!

The area of the octagon in your drawing is 1086 ! 

I just double checked!

If your teacher marks it wrong, ask her to explain where in hell she got that .4 from!!

anonymous · Answer

I'll mosey along here, but seriously, please keep me updated on this thing, because 1086.4 is just flat out wrong.
