triangle help !!
PQR is an equilateral triangle. The point U is the mid point of PR. Points T and S divide QP and QR in the ration1:2. The point of intersection of PS, RT and QU is X. If the area of triangle QSX is 1 square unit, what is the area, in square units of triangle PQR?
Any idea appreciated!!!

Re: triangle help !!
If it helps, I drew this as accurately as I could and I'm reasonably certain the answer is 12.5 to the nearest tenth. (I measured it as 17300/1386)
Tricky one to figure out geometrically though.
Why did the vector cross the road?
It wanted to be normal.
