How many acres is a 30 ft by 100 ft lot?

To find the area of a lot that measures 30 feet by 100 feet, you multiply the length by the width: 30 ft × 100 ft = 3,000 square feet. To convert square feet to acres, you divide by 43,560 (the number of square feet in an acre). Therefore, 3,000 square feet is approximately 0.069 acres.
