13 feet x 3 feet = 39 square feet.
Total square feet: 169.0 (13 x 13 = 169)
13 feet = 3 962.4 millimetres
Total square feet: 429.0
19*13 = 247 square feet.
3 linear measurements yeild VOLUME not AREA.
13 feet 10 inches is 4.22 meters.
13 times 20 = 260 square feet
I am assuming this is a circular pool. The answer is Pi r^2 which comes to 572.5SF
73multiply by3 = 219
35divided by3 = 11.666666666666666
15 feet * 13 feet = 4.572 metres * 3.962 metres = 18.116 sq metres.
13 feet is 3.9624 metres, 17 feet is 5.1816 metres - multiply the two together and you get 20.5316 m2
