Answer:
12 minutes
Step-by-step explanation:
Time spent for 2 patches = 4 minutes
Time spent for 1 patch = 4 / 2 = 2 minutes
Time spent for 6 patches = 2 x 6 = 12 minutes
The area of a square can be calculated by using this formula:
![A=s^2](https://tex.z-dn.net/?f=A%3Ds%5E2)
Where "s" is the length of a side of the square.
In this case, you can identify that:
![s=9.7ft](https://tex.z-dn.net/?f=s%3D9.7ft)
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](https://tex.z-dn.net/?f=7%3E5)
You must round up:
![s\approx10ft](https://tex.z-dn.net/?f=s%5Capprox10ft)
2. Knowing that:
![10^2=10\cdot10](https://tex.z-dn.net/?f=10%5E2%3D10%5Ccdot10)
You can determine that:
![A\approx100ft^2](https://tex.z-dn.net/?f=A%5Capprox100ft%5E2)
Hence, the answer is: Option C.
