we can always divide the rhombus into two equal parts like this.|dw:1371937685454:dw| we know that all the sides of a rhombus are equal.
AB=BC=CD=DA=8 in. find the area of the triangle ABC. and then twice of that. that's the area of the rhombus.
32in^2
???right???

its \[area=\frac{ 1 }{ 2 }8^{2}\sin 60\] plug in sin60=(sqroot 3)/2 and then twice the area.
total area= \[8^{2} \frac{ \sqrt{3} }{ 2 }\] \[=32\sqrt{3} inch ^{2}\]

i did it like that so i timed 8*8 and /2
AC and BD might not be 8in.
