 Question from Linda: How long and wide is an 80-acre piece of land that is square? How long and wide is a 160-acre piece of land that is square?

Hi Linda,

I need to know how many square feet there are in 80 acres. I am a Macintosh user so I asked Siri.

Penny:
Hey Siri, how many square feet are there in 80 Acres?

Siri:
80 acres are 3,844,800 square feet.

The area of a square is the side length time the side length so

$\mbox{(side length)}^2 = 3,844,800.$

Penny:
Hey Siri what is the square root of three million, eight hundred and forty-four thousand eight hundred?
Siri:
The square root of three million, eight hundred and forty-four thousand eight hundred is approximately 1,960.82.

Hence a 80 acre square is 1,960.82 feet by 1,960.82 feet.

You can answer the 160 acre question.
