the 2 is the symbol for squared. it means that you multiply that amount of feet by itself, to get square feet. like 3x3=9, or 9= the square of 3, or 3=the square root of 9.

8 FOOT above is a linear solution, looks to me like dimensions so its 8 square feet, 8ft^2
The area of a circle is pi*(radius)^2. If the 8 ft is the diameter, the area is pi*(4 ft)^2~=50.27 ft^2 (ft^2 is square feet)
1 m² is approximately 10.76 ft². Then: 250 m² * 10.76 ft² / m² ≈ 2691 ft²
Square inscribed a 30 ft diameter has a diagonal equal to 30 ft. Use the Pythagorean theorem, and side^2 + side^2 = 30^2 2s^2 = 900 s^2 = 450 side length = square root of 450, simplify 15sqrt(2) = s Area = s^2 = 450 square feet Perimeter = 4s = 4*15*sqrt(2) = 60 times the square root of 2
8ft by 4 ft by 2 ft is a measure of volume. Simple dimensional analysis teaches that a volume cannot be related to an area (square feet) without additional information.
