Using your hint ,applied on $\triangle ABC$ ,where $AB=AC =10$ cm. and $\angle BAC=30^ \circ ,BD \perp AC$, I see that $\triangle ABC= \frac 12 \times 10 \times BD=5BD$ where $BD=\sqrt {10^2-AD^2}$. Now,I am stuck. Can someone help?

Apr11 accepted How to find the area of the following triangle Apr11 comment How to find the area of the following triangle I still could not finish it . We can find the area of rhombus in 2 ways and from that we get the relation $20 h=\frac12 ab$, where $h$ is the height of the rhombus and $a,b$ are the lengths of diagonals.. Now, I am stuck. Apr11 comment How to find the area of the following triangle I do not get it...It will give me rhombus with two opposite angles of $45 ^{\circ}$ each and other two opposite angles of $135 ^{\circ}$ each. Apr11 comment How to find the area of the following triangle wow..got your point..Then it becomes rhombus...I think i can take it forword.. Apr11 comment How to find the area of the following triangle Thanks for the answer but I can not use $\sin$ related theorem. Apr11 asked How to find the area of the following triangle
