Regional Classifications Quick Check 1 of 51 of 5 Items Question Which statement best summarizes the difference between formal and functional regions?(1 point) Responses A formal region is an area on Earth’s surface defined by relatively unchanging cultural or physical traits, often associated with a formal boundary. A functional region is an area characterized by one or more activities occurring in that area, whose boundary is usually more loosely defined. A formal region is an area on Earth’s surface defined by relatively unchanging cultural or physical traits, often associated with a formal boundary. A functional region is an area characterized by one or more activities occurring in that area, whose boundary is usually more loosely defined. A functional region is an area on Earth’s surface with boundaries that are based on an individual’s perceptions, thoughts, and/or knowledge of people and their cultural traits, physical geography, and/or the build environment. A formal region is an area characterized by one or more activities occurring in that area, whose boundary is usually more loosely defined.

To evaluate u + xy, we substitute the given values:

u + xy = 18 + (10)(8) = 18 + 80 = 98

Therefore, the value of u + xy is 98.

To find the length of a side of the square field, we can take the square root of the area.

√479 ≈ 21.9

Rounding to the nearest foot, the approximate length of a side of the field is 22 feet. This is because the square root of 479 is closer to 22 than it is to 21.
