The short answer: 1.5 acres comes to 65,340 ft². That is 1.5 multiplied by 43,560, the factor fixed by definition, carried to full precision before anything is rounded for display.
1.5 acres is 6070.28 m², a square 77.91 m on a side. For comparison a full-size football pitch is a little over 1.7 acres, and a US residential lot is commonly a quarter of one.
The result sits 10 ft² short of 65,350 ft², so if you need a round figure to quote, 65,350 ft² is the honest nearest one. Plenty of people do this in their head: multiply by 44,000 instead of using the exact factor 43,560. At 1.5 that shortcut gives 66,000 square feet, off by 660 square feet or about 1.01%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
