The length of the diagonal measures 54.2 meters.
We have given that,
A rectangular swimming pool is 21 meters
wide and 50 meters long.
We have to determine the length of the diagonal.
What is the Pythagorean theorem?
a² + b² = c²
a and b are sides of the triangle and c is the hypotenuse
a = 21,
b = 50
c = diagonal
21² + 50² = c²
441 + 2500 = c²
2941 = c²
Taking square root on both side
√2941 = c
54.23098 = c
54.2 = c
Therefore the length of the diagonal measures 54.2 meters.
