"PRQSTU is a regular hexagon of side 2 units. PQ,QR and RS represent vectorsa,bandcrespectively. Find the value ofa.(b + c)

The hexagon is a regular hexagon starting at the far left (ie pointing left) with P then anti clockwise through U at the top left.

2. Relevant equations

None that I can think of.

3. The attempt at a solution

I really don't know where to start. I've guessed thata(PQ) = -c. But I don't know where to go from there and now I'm really confused.

Any help greatly appreciated.
