It is a measurement of area equal to 80 feet wide and 80 feet long.
80 ft * 60 ft = 80*60 sq ft = 4800 sq ft
80 ft X 544.5 ft = 43560 square ft which is equal to 1 acre.
80 sq ft
8 ft x 10 ft = 80 ft2 or 80 square feet.
1120 square feet
80 square feet
9 sq ft = 1 sq yd so 80 sq ft = 80/9 = 8.88... sq yards.
6400 square ft 80 multiplied by 80 = 6400 square ft
10 ft x 8 ft = 80 square feet.
If the diameter is 80 ft then the area is 5026.54 sq ft
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.
There are 144 inches in a square foot so, 144 x 80 is 11520 inches in 80 square feet.
