[    [ __________________ _]   ]
[______________________ _ _]

1.  Given the diagram above, how do I write a polynomial that represents the total area of tthe castle and the moat?

2.  How do I find the combined area if the moat is 10 feet wide?

3.  If the moat is also 10 feet deep, how do I calculate how many gallons of water are in the moat if 1 gallon = 0.134ft^3?  Round to the gallon.

A big thank you.
