**Bosnian**, Tuesday, October 19, 2010 at 12:03pmh-hight , a-thirth side of triangle

al-angle ALPHA , A-area

sin(al)=(h/6) , h=6*sin(al)

cos(al)=(a/2)/6 =( a/12) , a=12*cos(al)

A=(1/2)a*h=(1/2)*6*sin(al)*12*cos(al)

=(1/2)*72*sin(al)*cos(al) =36*sin(al)*cos(al) =18*(2*sin(al)*cos(al))=18*sin(2al)

=dA/dal)=18*2*cos(2al=0 , cos(2al)=0

2al=90 al=45

**Bosnian**, Tuesday, October 19, 2010 at 12:20pmh=6*sin(45)=6*(1/2)=6/2

a=12*12*cos(45)=12*(1/2)=12/2

A=(1/2)a*h=(1/2)6/2*12/2

=(1/2)*(1/2)/*1/2)*72=(1/2)*(1/)*72

=(1/4)*72= 18

Largest posible area= 18

Area=(1/2)*(1/2)*72=18
