Text{Square Feet} 2 x 43,560 87,120 square feet.
Historical Context
The concept of an acre is deeply rooted in history. In the past, an acre was defined as the amount of land that could be plowed in a day by a person with an ox. Today, it is commonly understood as a measure of 43,560 square feet. This measurement is still used in many practical applications, particularly in real estate and land development.

Text{Square Mile} 5280 x 5280 27,878,400 square feet
Therefore, to find the number of square feet in 640 acres:
Text{Square Feet} 640 x 43,560 27,878,400 square feet.
Measurement of Land in Chains
Another interesting aspect of land measurement is the use of chains. A chain is a unit of length equal to 66 feet. Historically, a furlong, which is 1/8 of a mile or 660 feet, was often used to measure land. This system was based on the length a team of oxen could plow in one day.
To measure one square acre using chains, you can use the following:
One chain is 66 feet. Ten chains make up one furlong, which is 660 feet. Therefore, one square acre is 66 feet by 660 feet.Multiplying these gives a total of 43,560 square feet:
Square Feet 66 x 660 43,560 square feet.
