A foot is a measure of length or distance in 1-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

To determine how many squares fit into 1500 square feet, note that one square is defined as 100 square feet. Therefore, you can divide 1500 by 100: ( 1500 \div 100 = 15 ). This means there are 15 squares in 1500 square feet.

100 feet by 100 feet is 10,000 square feet which is equivalent to about 0.2296 acres. Improvement: 1 Acre=43560 Square feet. Therefore 100 Ftx100 Ft (10000 SqFt) is= 0.2295684 Acres
