How many feet are in the perimeter of 1 acre?

That would depend upon the shape of the one acre, which contains 43,560 square feet.
If it is a perfect circle, an acre has a radius of (sqrt 43560 / 3.1415) 117 feet 9 inches.
If it is square, then each side has a length of (sqrt 43560) 208 feet 8.5 inches.
For other shapes, ask the math FAQ. If the acre is square, then each side would be 208' 8.5"
So the perimeter would be 834.8 feet.
However, if the shape is other than a square, then the perimeter would vary. An acre measures 43,560 square feet, and that could be made up by any number of difference rectangles (to say nothing of non-regular shapes) which could range from the square mentioned above to one measuring one foot by 43,560 feet. SUch an unlikely rectangle would have a perimeter of 87,112 feet.
