Question

A square patio has an area of 170 square feet. How long is each side of the patio to the nearest tenth?

Answer 1

Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1

You can check your work by multiplying 13.1 by 13.1 which equals 170.3
