Which measurement is closest to the size of an acre?

1. Half a football field

2. Two square kilometers

3. About 75% of a soccer field

4. A full-size baseball field

The correct answer is: Half a football field

An acre is a unit of area that is defined as 43,560 square feet. When visualizing this area, it's helpful to compare it to common field sizes. A standard American football field, including the end zones, is about 57,600 square feet, meaning an acre is slightly less than a football field. Therefore, stating that an acre is close to half a football field provides a reasonable approximation, as it suggests a simpler understanding of the size for those familiar with sports fields. The other options do not accurately represent the size of an acre. For instance, two square kilometers is significantly larger than an acre, as one square kilometer equals 247.1 acres. Similarly, while a soccer field's size can vary, it's generally around 68,000 square feet, which is more substantial than an acre. Finally, a full-size baseball field varies in dimensions, but the area also often exceeds that of an acre, furthering the inaccuracy when comparing those options to it.
