@timo86m Help with mine?
do you know trig? or does this only require pythogoras theorem?

It should only require Pythagoras theorem. It is merely Geometry.
But the Sq Rt is what confuses me.
I tried using the 30-60-90 ratio and i got the answer: 2 times sqrt of 1.5 sq in which is wrong.

Don't i take half of 4√3 since its the hypotunese?
|dw:1346873167383:dw| once you have a then a*2 would be height
And how do i find A? A is what?
a is 4 i think the height is 8
SO it would be area= 8 times the sqrt of 3?
then i think it is just 8*8 the area Something seems odd tho. THe figure is not to scale or i am wrong.
i did it wrong
all you have to do is find height then it is simply 8*h
But how will that get me a sq rt?
i found where i gone wrong lol
Lol
|dw:1346874388605:dw|
a=2*sqrt(3) So h = 2*sqrt(3)*sqrt(3) and A=h*b can you do that?
The height is √3 correct?
a=2*sqrt(3) So h = 2*sqrt(3)*sqrt(3) and A=h*b can you do that?
19-3= 16 times √3
Thanks man!
I got it.
:)
