How long is 80 square feet?

Answer 1

The question has no sensible answer.

80 square feet is a measure of area and that cannot be converted to a distance or length.

The most compact form, for an area of 80 sq feet, is a circle of radius just over 5 ft (5.046 ft).

A square of sides sqrt(80) = 8.944 ft would have an are aof 80 square feet.

Suppose L is any length greater than 8.944 ft, and B = 80/L feet, then the area of a rectangle whose sides are L and B would have an area of 80 sq ft.

So, L the length could be 80 feet (B = 1 ft)

or 8,000 ft (B = 0.01 ft)

or 8 million ft (B = 0.00001 ft)

or as high a number as you like.
