The answer is 2112ft
528ft is roughly 1/10th of a mile.
You can't tell. The area doesn't tell you the dimensions. There are an infinite number of shapes, all with different dimensions, that all have areas of 1 acre. "One acre" only tells you how much ground it covers, but the outline of that area can have any shape. If your acre is circular, then its diameter is 235.5-ft. If it's square, then its sides are all 208.7-ft If it's a rectangle, then there are an infinite number of possibilities. Here are a few. They're all 1 acre: If it's 1 mile long, then it's 8ft 3in wide. If it's 4,840ft long, then it's 9ft wide. If it's 3,600ft long, then it's 12.1ft wide. If it's 528ft long, then it's 82.5ft wide. If it's 484ft long, then it's 90ft wide. If it's 360ft long, then it's 121ft wide. If it's 242ft long, then it's 180ft wide.
