An American football field, including end zones, is 360 feet long and 160 feet wide. If you needed to describe it for someone in Europe using the metric system, which one of the following quantities would be closest to its area in square meters?

An american football field is about 5.35 square kilometers.

Step-by-step explanation:

Remember that 1 foot is equivalent to 0.304 meters. First multiply 360 * 0.304 to get 109.73 meters. They multiply 160 * 0.304 to get 48.77. Multiply 109.73 and 48.77 to get 5351.53 square meters or about 5.35 square kilometers
