1. The problem states the Pythagorean Theorem: $$a^2 + b^2 = c^2$$ and gives values $a=7$ and $b=11$. We need to find $c^2$.
2. First, calculate $a^2$ and $b^2$:
$$a^2 = 7^2 = 7 \times 7 = 49$$
$$b^2 = 11^2 = 11 \times 11 = 121$$
3. Now, add $a^2$ and $b^2$ to find $c^2$:
$$c^2 = a^2 + b^2 = 49 + 121 = 170$$
4. Therefore, $c^2$ equals 170.
The correct answer is A. 170.
