Use the law of Pythagoras to calculate the diagonal.
The idea here is to use the Rule of Pythagoras, a2 + b2 = c2, or c = square root of (a2 + b2). "c" in this case is the diagonal. (The rule applies when a and b are at right angles; I am assuming here that the swimming pool is rectangular, which is usually the case.)
The length of the diagonal is about 16.03 feet.
length of diagonal of 20 of a 20 feet and 15 width.
The length of a rectangle that has a diagonal of 25 feet and a width of 15 feet is 20 feet.
The diagonal is approximately 38.42 feet.
Using Pythagoras: 322+362 = 2320 and the square root of this is the length of the diagonal
Using Pythagoras' theorem the length of the diagonal is 20 feet
Diagonal = 18.867 feet.
100 Feet... pathway is bisecting the rectangle into 2 right-angled triangles. Length of the hypotenuse is the length of pathway
The diagonal is 1.414 feet.
The diagonal is 7.21 feet.
The diagonal is about 28.3 feet.
