What does a square mile equal in square feet?

To determine how many square feet are in a square mile, it's essential to understand the relationship between miles and feet. One mile is equal to 5,280 feet. To find the area of a square mile, one would multiply the length of one side (1 mile) by itself.

Calculating this:

1 mile = 5,280 feet

Area = 5,280 feet x 5,280 feet = 27,878,400 square feet.

Thus, a square mile equals 27,878,400 square feet, making it the correct answer. This understanding is key when dealing with real estate or title insurance, as these measurements often come into play in property assessments and land descriptions.
