The area is 21*31 = 651 square feet.

Area: 43*57 = 2451 square feet Perimeter: 43+57+43+57 = 200 feet

You have two 43-ft sides = 86-ft and two 20-ft sides = 40-ft. Total perimeter = 126-ft.

If its diameter is 43 ft then its circumference is pi*43 = 135.088 ft to 3 dp

21-ft x 22-ft = 462 ft2

The question cannot be answered. An acre is an area of 43560 sq feet. This may be in the form of a rectangle measuring: 1 ft * 43560 ft, or 10 ft * 4356 ft or 100 ft *435.6 ft etc or 2 ft * 21780 ft, or 20 ft * 2178 ft etc etc. And there is no reason for these numbers to be rational. Furthermore, there is no reason for the area to be quadrangular. It could be circular, oval or simply irregular.

First of all, your 52" pool will have 48" of water. An oval pool is actually an obround consisting of two arcs and a rectangular area between them. The rectangular area is 8 ft x 16 ft, volume of which is 512 cu ft. The two arcs together makes a perfect circle of 16 ft in diameter, and has a volume of 805 cu. ft. Added together and converted to liquid volume is 11,348 U.S. gallons of water.
