General Contractor Practice Exam

Which of the following represents the measurement of an acre?

1. 210 feet x 210 feet

2. 43,560 square feet

3. 160 square meters

4. 1/10 of a hectare

The correct answer is: 43,560 square feet

The measurement of an acre is defined as 43,560 square feet. This unit of area is commonly used in the United States and represents a specific size of land. Understanding the dimensions of an acre is important for various applications, including real estate, landscaping, and agriculture. To elaborate, when measuring land, one acre is essentially a square that is 208.71 feet on each side or can be visualized in other rectangular dimensions, as long as the total area adds up to 43,560 square feet. This is why option B accurately represents the measurement of an acre. The other choices relate to different measurements or conversions that do not accurately define an acre. For example, while 210 feet by 210 feet may seem close to an acre, it actually measures about 44,100 square feet, which exceeds an acre. The option regarding square meters does not reflect the standardized acre measurement, as an acre is significantly larger than 160 square meters. Lastly, 1/10 of a hectare is equivalent to about 1,000 square meters, which also does not align with the acre measurement. Hence, option B is the only correct representation of an acre.
