If the linear footage was measured around the whole edge of the pool the the sq ft = 689.0625 sq ft However if this is only the length of the pool then there is no way to work it out,
Radius squared times pi 12X12=144X3.14=452.16 452 sq. ft.
Can't be done. You need to specify the width and length of the pool. That is because the area of a long, narrow pool is not the same as the area of a pool that is closer to square.
5m * 20m = 100 m2 = 1076.4 sq ft (approx)
A rug with a circumference of 6 ft has an area of 2.86 sq ft, approx.
26*11 = 286 sq metres
NO they differ by one dimension.
6 ft X 6ft pool would be 36 sq ft 6 ft round pool would be 28.26 sq ft
97.44 sq feet
43560 sq ft
900 sq ft 9x100=900 sq ft
If the floor of the pool is of uniform gradient then: Pool bottom = 18' x 36' = 648 sq ft Shallow wall = 18' x 3' = 54 sq ft Deep wall = 18' x 8' = 144 sq ft Two Sides = 2*{0.5*36*(3+8)} = 396 sq ft (they are trapezium-shaped). Total = 1242 square feet. Strictly speaking, if the pool is 36' long, the sloping length of the bottom is 36.35' (approx), so the pool bottom is 654.22 sq ft and the total is 1248.22 sq ft.
