Answer:
○ C) 256 in.²
Step-by-step explanation:
{a}^{2} + 2a \sqrt{ \frac{ {a}^{2}}{4} + {h}^{2} } = S. A. \\ \\ {8}^{2} + 2(8) \sqrt{ \frac{{8}^{2}}{4} + {12}^{2}} = 64 + 64\sqrt{10}\\ \\ 64\sqrt{10} ≈ 266,3857703 ≈ 256

The amount that was invested 17 years ago is $2064.25.
The interest earned is $7935.75.
<h3>What is the amount invested 17 years ago?</h3>
The formula that would used to determine the amount that was invested 17 years ago is:
P = FV / (1 + r)^nm
Where:
- FV = Future value = 10,000
- P = Present value
- R = interest rate = 9.5 / 2 = 4.75%
- m = number of compounding = 2
- N = number of years = 17
10,000 / (1.0475)^(17 x 2) = $2064.25
Interest earned = 10,000 - 2064.25 = $7935.75
