The area of a square can be calculated by using this formula:


A=s^2

Where "s" is the length of a side of the square.

In this case, you can identify that:


s=9.7ft

Then, in order to estimate the area of the square, you can follow these steps:

1. Round the length "s" to the nearest whole number. Since the first digit after the Decimal point is 7 and:


7>5

You must round up:


s\approx10ft

2. Knowing that:


10^2=10\cdot10

You can determine that:


A\approx100ft^2

Hence, the answer is: Option C.
